The sea turtle science and recovery program at Padre Island National Seashore is a part of overall global efforts to help recover the populations of seven species of threatened and endangered sea turtles. Five of the world's seven sea turtle species are found in the Gulf of Mexico: leatherback,hawksbill, green, loggerhead and Kemp's ridley. Nests from all five species have been documented at Padre Island National Seashore. The National Seashore is the only location in Texas where nests from all five species have been documented. Park waters also provide important habitat for these species.

These magnificent marine animals, once abundant in the oceans, declined during the last century. Human development on turtle nesting beaches, harvesting of the eggs, slaughtering for food and consumer products, and incidental capturing by fisheries are to blame for dwindling turtle populations. Each of the five sea turtle species of the Gulf is now classified as either threatened or endangered and could become extinct unless steps are taken to protect and enhance its populations.

The Division of Sea Turtle Science and Recovery at Padre Island National Seashore conducts an active science, conservation, and public education program on behalf of the five sea turtle species that occur at the park. This work is local, statewide, national, and international in scope, in partnership with numerous entities. This work receives extensive community support and media coverage.

The largest program conducted by this Division is the Kemp's Ridley Sea Turtle Recovery Project. This program is long-term and involves many entities in the U.S. and Mexico.

Another large, long-term project is the Sea Turtle Stranding and Salvage Network (STSSN). The Division participates in this network and the Division Chief is the Texas Coordinator of the STSSN. As Texas Coordinator, the Division Chief (with help of others in the Division) maintains the tally of sea turtles found stranded (washed ashore or floating, alive or dead) on the Texas coast. The Division Chief also maintains the tally of sea turtle nests found on the Texas coast and provides technical assistance and training to others working in the state with stranded and nesting turtles.

Division personnel have led or participated in several studies of sea turtles. Many of these studies have been collaborative with other researchers in the U.S. and Mexico. These studies have addressed priority items in the Recovery Plans for the various species and have produced information that has increased understanding of these species and aided with their conservation.

Division personnel led studies that utilized satellite telemetry to track the movements of nesting Kemp's ridley turtles, adult male Kemp's ridley turtles, juvenile green sea turtles,and adult green sea turtles. The green sea turtle tracking study was part of a larger study of the distribution, residency, and seasonal movements of green sea turtles in Texas, which also involved directed capture by research netting and examination of stranding data. They also participated in studies that used STSSN data to evaluate mortality.

Data continue to be gathered in collaboration with others on nesting and stranding trends in Texas, results of the imprinting and head-starting, life-history parameters for nesting turtles and nests, incubation temperatures and sex ratios, foraging ecology, genetics, and other topics.

Padre Island National Seashore is the longest stretch of undeveloped barrier island in the world. In addition to its 70 miles of protected coastline, other important ecosystems abound, including rare coastal prairie, a complex and dynamic dune system, wind tidal flats teeming with life, and the Laguna Madre, one of the few hypersaline lagoon environments left in the world. The National Seashore and surrounding waters provide important habitat for marine and terrestrial plants and animals, including a number of rare, threatened, and endangered species.

Situated along the Central Flyway, Padre Island is a globally important area for over 380 migratory, overwintering, and resident bird species (nearly half of all bird species documented in North America). Thirteen of these species are considered species of concern, threatened, or endangered.

Also of significant concern at Padre Island is the Kemp's ridley sea turtle, the most endangered sea turtle species in the world, which nests on the beach from late April through mid-July.The National Seashore is also one of the few places people can see newly hatched Kemp’s ridleys released into the wild.

With urban sprawl, climate change, pollution, and other detrimental factors continuing to threaten wildlife, critical ecosystems, and wild places worldwide, Padre Island remains a place where nature can balance itself, and where people can always visit to experience true quiet, solitude and a night sky filled with bright starlight.

The Padre Island National Sea Shore is 134,000 acres and was established in 1962. You can see first hand the sea shore at its most natural state. Untouched by development and maintained to preserve it's natural state. You won't want to miss out on this wonder of nature. 

At Bruton Motor Sports we promote getting out and enjoying the outdoors and nature at it's finest. Families will enjoy this pristine natural wonder. We are proud to call Padre Island home and hope you will visit one of America's finest National Parks.

·         Unsurpassed powertrain warranty – five years/100,000 miles
August 25, 2014 , Auburn Hills, Mich. - Ram takes heavy-duty towing and hauling seriously. With this week’s start of 2015 model year Ram 2500 and 3500 Heavy Duty production, the truck world’s “King of the Hill” further adds to its most-capable claims.

Ram 3500 models will offer increased torque ratings of 865 lb.-ft. and an increased payload of 7,390 pounds, while maintaining a class leading maximum tow rating of 30,000 pounds.

Ram is the only automaker to back its heavy-duty towing claims using SAE J2807 testing criteria.

"Ram maintains leadership throughout its pickup line by offering best-in-class fuel efficiency with our Ram 1500 EcoDiesel at 28 MPG, best-in-class towing at 30,000 pounds, best-in-class power at 865 lb.-ft. and best-in-class payload at 7,390 pounds with our Ram 3500," said Bob Hegbloom, Head of Ram Truck Brand, Chrysler Group LLC. "Ram owns best-in-class attributes in the areas that are most important to truck customers.”

Working closely with Cummins, a more aggressive fuel delivery and turbo boost calibration to the 6.7-liter I-6 produces an additional 15 lb.-ft. of torque. This improvement places the coveted engine ahead of the competition with 865 lb.-ft. of torque, while maintaining performance and EPA compliance. The Ram 3500 continues towing leadership at 30,000 pounds and adds a new notch in its belt with a chart-topping payload of 7,390 pounds. The payload claim was made possible by challenging the Ram 3500 6.4-liter HEMI V-8 pickup with an increase in GVWR of 100 pounds, now 13,800 pounds GVWR.

“Ram has driven innovation in the heavy duty segments and intelligently engineered a better truck than our competitors, including a 30,000 pound towing monster,” said Mike Cairns, Director— Ram Truck Engineering, Chrysler Group LLC. “Our 2015 Ram Heavy Duty Trucks own all three relevant titles in the segment: towing, payload and power, while delivering an impressive level of comfort and features unavailable elsewhere in the market.”
Ram 2500 and 3500 Heavy Duty pickup trucks are assembled at Chrysler Group’s Saltillo Truck Assembly Plant in Coahuila, Mexico.

With Chrysler Group’s  6.4-liter HEMI V-8, the Ram Heavy Duty delivers to best-in-class horsepower and best-in-class torque among pickups with gasoline engines. Compelling numbers tell the story of the 16-valve engine with 410 horsepower (306 kW) at 5,600 rpm and a peak torque rating of 429 lb.-ft.(582 N•m), at 4,000 rpm.

Other engine options include the 5.7-liter HEMI V-8, standard equipment for the Ram 2500 and 3500 (SRW). The engine produces 383 horsepower at 5,600 rpm and generates peak torque of 400 lb.-ft. of torque at 4,000 rpm. The 5.7-liter HEMI V-8 is mated to a 66RFE six-speed automatic transmission.

The renowned 6.7-liter Cummins Turbo Diesel I-6 is available in three versions. The first version is paired with Ram’s segment exclusive six-speed manual transmission. This combination delivers 350 horsepower at 2,800 rpm and 660 lb.-ft. of torque at 1,400 rpm. The second option matches the Cummins to the 68RFE six-speed automatic transmission. The diesel engine cranks out 370 horsepower at 2,800 rpm with 800 lb.-ft. of torque at 1,600 rpm.

Dominating torque charts, the 6.7-liter Cummins High-Output Turbo Diesel I-6 for Ram 3500 is paired with the Aisin six-speed automatic transmission (AS69RC), leaving no doubt to Ram Heavy Duty’s capability. In addition to 385 horsepower at 2,800 rpm, the most powerful Cummins generates best-in-class torque of 865 lb.-ft. at 1,700 rpm.

Ram Heavy Duty trucks feature frames built with high-strength 50,000 psi steel, including eight separate cross-members, hydroformed main rails and fully boxed rear rails for optimal strength and mass efficiency. Chassis controls on the Ram Heavy Duty ensure reduced noise, vibration and harshness (NVH) measurements and improve ride and handling characteristics. Standard electronic stability control (ESC) on single and dual-rear-wheel equipped trucks, and body-to-frame hydro-mounts provide improved ride quality.

Center frame rail sections are roll-formed, an efficient means for maintaining consistent strength in less complex longitudinal sections. In the rear portion of the frame, the structure includes fully boxed rear rails and a factory-installed rear axle cross-member with provisions for fifth wheel and gooseneck hitches.

Heavy Duty trucks generally have suspension equipped for constant, heavy payloads. This leads to a harsher ride when unloaded. Ram innovation leads again. The Ram 2500 takes lessons learned from the Ram 1500 with a segment exclusive five-link coil rear suspension system. Loaded or unloaded, the 5-link coil system provides best-in-class ride and handling. The five-link coil design incorporates support at all major points of force. Leaf spring suspensions struggle to combat axle wrap by using staggered shock absorbers (one mounted on the front of the axle tube and one mounted on the rear of the axle tube). The superior design of the five-link coil system functionally resists unwanted axle rotation. Leaf spring configurations also lack lateral support, forcing the leaf ends and shackles to hold against lateral loads — a task they're not particularly good at and one reason competitive leaf-sprung rear suspensions shutter on rough surfaces. Additionally, the Ram 2500 offers a rear air suspension system for automatic load leveling and greater versatility.

The Ram 3500 continues to feature the rear Hotchkiss leaf spring system, but offers a supplemental air suspension system (late availability). By adding supplemental air bags to the rear suspension, Ram engineers were able to soften the leaf springs, allowing for more unladed suspension movement— even with a best-in-class 30,000-lb. trailer.

In the front, the Ram Heavy Duty line features an advanced three-link front suspension to ensure roll stiffness. Greater roll stiffness, also known as body roll, is an important characteristic in taller vehicles and especially trucks with heavy payloads. Roll stiffness is measured by the amount the truck’s body tips side-to-side, independently of the wheels, during cornering.

The Ram Heavy Duty comes equipped with robust engine, transmission and body mounts, including pioneering hydro-mounts at C-pillar positions for class-leading noise, vibration and harshness (NVH) characteristics despite the truck’s aptitude for higher payloads and towing.

The Ram Heavy Duty trucks feature a factory-installed seven-pin trailer tow connector in the truck bed, included with the optional fifth wheel or gooseneck tow prep package. Ram is unmatched in terms of offering the most complete “hitch ‘n go” towing prep package found anywhere in the heavy-duty category. Additionally, Ram features a standard Class 5 receiver hitch with four- and seven-pin connectors on the bumper. A tailgate handle-mounted, rear high-definition camera backup system is available with dynamic imaging in the 8.4-inch display. Also, the cargo-view camera located in the center high-mounted stop light (CHMSL) provides a view of the bed for easier connection to fifth wheel or gooseneck trailers as well as monitoring bed loads.

Ram Heavy Duty customers can enjoy the convenience of an exclusive cargo camera, power folding mirrors and a combination, power rear-sliding window with defrost. Also, central locking includes the RamBox cargo management system and tailgate power locks, creating a convenient solution for locking all exterior doors and storage with one push of a button. Auto rain-sensing wipers and SmartBeam headlamps also are available, adding to a truckload of content offered in Ram Heavy Duty.

Total Cost Of Ownership And Unsurpassed Powertrain Warranty - Five Years/ 100,000 Miles
Operating costs are of great consideration for owners who use their trucks for work. The Ram Heavy Duty holds class-leading features in:
  • Extended maintenance cycle (oil change of 15,000, fuel filter life on diesel)
  • Brake life with advanced engine exhaust brake and largest brakes in the segment

The 2015 Ram Heavy Duty is backed with an unsurpassed five-year/100,000-mile Powertrain Limited Warranty. The powertrain-limited warranty covers the cost of all parts and labor needed to repair a covered powertrain component – engine, transmission and drive system. Coverage also includes free towing to the nearest Ram Truck dealer, if necessary. The warranty also is transferable allowing customers who sell their truck during the warranty period to pass the coverage on to the new owner. The standard five-year/36,000-mile Basic Limited Warranty provides bumper-to-bumper coverage for the Ram Heavy Duty, from the body to the electrical system.

About Ram Truck Brand
Since its launch as a stand-alone division in 2009, the Ram Truck Brand has steadily emerged as an industry leader with one goal: to build the best pickup trucks and commercial vehicles in the industry.

Creating a distinct identity for Ram Trucks has allowed the brand to concentrate on core customers and features they find valuable.

Corvette Engine Repeats Win as WardsAuto 10 Best

6.2L LT1 among industry’s elite powerplants

DETROITThe high performance, technology-packed LT1 Small Block 6.2L V8 that powers the 2015 Corvette Stingray is a Ward’s 10 Best Engine for 2015. The engine also was recognized with this award in 2014.

WardsAuto reviewed 37 engines and propulsion systems from 12 manufacturers in this year’s competition, which looked at power, fuel efficiency, new technology and refinement and compared the attributes with data for similar engines.

“This recognition is another step in earning customers for life,” said Dan Nicholson, vice president, GM Global Powertrain. Having the WardsAuto experts choose the LT1 as one of the best in the industry two years in a row is proof of what this Powertrain team can deliver – uncompromised performance, durability and efficiency that helps make the Stingray one of the best sports cars in the world today.”

The LT1 Small Block technologies contribute to making the new Corvette the quickest, most powerful and most fuel-efficient standard Corvette ever. The engine delivers an SAE-certified 460 horsepower, helping propel the car from 0-60 in 3.8 seconds and a quarter mile in 12 seconds while offering EPA-estimated 29 mpg highway with an 8-speed automatic or 7-speed manual transmission.

“The 6.2L LT1 V-8 is the heart and soul of the seventh-generation Chevrolet Corvette, and it proudly upholds the 60-year legacy of small-block engines from General Motors,” said Tom Murphy, executive editor of WardsAuto World digital magazine. “This one's been re-engineered from head to torque converter, and the LT1 is the crown jewel of this massive engine family.”

“In the Corvette, this 460-hp V-8 barks with authority, delivering an exhaust note reminiscent of Detroit’s finest muscle cars. And it's efficient, too. WardsAuto editors flogging the 'Vette for more than 300 miles managed better than 20 mpg with the new 8-speed automatic.”

The LT1, part of the Gen 5 family of Small Block engines, combines several advanced technologies – direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing – to support an advanced combustion system.

Direct injection is a primary contributor to greater combustion efficiency by ensuring a more complete burn of the fuel in the air-fuel mixture. This is achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio.

Increased power and efficiency result from more than 10 million hours of computational analysis including computational fluid dynamics, to make the most of the combustion system, the direct injection fuel system, active fuel management and variable valve timing systems that support it. The combustion system itself benefited from 6 million hours of dedicated CPU analysis time.

Other variants of the Gen 5 Small Block include the 4.3L V6, 5.3L and 6.2L V8 truck engines offered in the Chevrolet Silverado, Suburban, Tahoe, the GMC Sierra pickups, Yukon XL and Cadillac Escalade SUVs. The LT1 is manufactured in Tonawanda, N.Y.

General Motors traces its roots back to 1908. GM has 10 joint ventures, two wholly owned foreign enterprises and more than 58,000 employees in China. GM and its joint ventures offer the broadest lineup of vehicles and brands among automakers in China. Passenger cars and commercial vehicles are sold under the Baojun, Buick, Cadillac, Chevrolet, Jiefang, Opel and Wuling brands. In 2013, GM sold nearly 3.2 million vehicles in China.

A 6.0L gas V-8/six-speed automatic powertrain is standard in all models. A Duramax 6.6L turbo-diesel is available, paired with the Allison 1000 six-speed automatic transmission.

Exterior highlights
The new truck cab is stronger, as well, with nearly two-thirds of the cab structure made from high-strength steel for a confident feel and improved safety. The rear doors on crew-cab models are larger, enabling easier entry and exit for rear-seat passengers, and revised seats create approximately two inches more rear legroom.

Structural reinforcements and other components also help stiffen the body, contributing to confident, quiet performance on the highway, with noticeably reduced vibrations on rough surfaces. They include an enhanced instrument panel support beam, which spans the width of the cab’s interior under the dashboard, features a new beam-to-floor brace that is four times stronger than before. It’s used with stronger instrument panel mounting brackets and a thicker tubular steering column jacket to enhance the steering column’s stiffness, reducing vibration that could otherwise be felt in the steering wheel.

New inlaid doors, which fit into body sides rather than wrapping over the roof, combine with new triple door seals to reduce wind noise and turbulence, helping quiet the cab. The front of the truck is also carefully sealed to provide efficient cooling with minimal aerodynamic drag, including a new grille opening reinforcement mounted over the radiator support and the frame. It is a primary contributor of the sealing process, enabling tailored alignment of the hood, fenders, bumper, grille and headlamps, for a tight fit between parts that enhances airflow through and around the truck.

·         Interior color/trim combinations: Jet Black, Jet Black/Dark Ash and Cocoa/Dune.

Onstar with 4G LTE
Technology is essential for those who work out of their truck, and the new OnStar with 4G LTE and standard built-in Wi-Fi hotspot provides a mobile hub for drivers and passengers to stay connected. It comes with a three-month/three-gigabyte data trial, after which the customer can purchase additional data.

4G LTE is the most current and fastest mobile data network – 10 times faster than 3G and 100 times faster than the previous generation of OnStar hardware. And with OnStar, it also offers stronger, broader coverage than smartphones on the same network and it’s easy to use: If the vehicle is on, the connection is on.

Powertrains that perform
Under the hood of the Silverado 3500HD, a Vortec 6.0L gas V-8 with variable valve timing is paired with the Hydra-Matic 6L90 six-speed automatic transmission as the standard powertrain offering. This combination delivers excellent performance and efficiency, with an emphasis on low-rpm performance. It is rated at 322 horsepower (268 kW) and 380 lb-ft of torque (515 Nm).

The Duramax 6.6L turbo-diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 3500HD models. Highlights of the Duramax diesel include:
  • 397 horsepower (296 kW) at 3,000 rpm
  • 765 lb-ft of torque (1,037 Nm) at 1,600 rpm
  • High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
  • Exhaust brake system that enables controlled vehicle slowdown on downhill grades with minimal brake actuation
  • Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills
  • Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel
  • B20 biodiesel capability for an alternative fueling option.

Benefits of the Allison 1000 include a driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the Tow/Haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.

On Duramax diesel models, the driver can also engage the diesel exhaust brake, which uses the variable vanes in the turbocharger to smoothly and quietly create additional backpressure in the engine to help slow the vehicle. The combination of the exhaust brake and the automatic transmission downshifts helps the driver maintain the desired speed, even on long, steep highway downgrades.

Drivers in cold-weather climates warm up more quickly with the Duramax 6.6L engine, which has a starting time on par with gas engines. Its glow plug cycle time takes no more than three seconds in temperatures as low as -20 F (-29 C).

Chassis, suspension and drivetrain
Silverado 3500HD Chassis Cab models are based on the robust, heavy-duty design of the Silverado 3500HD pickups, including a fully boxed, hydroformed front frame. The rear frame section features a reinforced C-section design developed for easy adaptation of custom bodies.

The front suspension is a short-long arm/torsion bar design with forged steel upper control arms and precision-machined cast iron lower control arms. Four different torsion bar rates support four front gross axle weight ratings to help stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.

At the rear is a proven semi-elliptical 7+1 leaf spring suspension for the standard dual-rear-wheel axle. All models area available in 2WD and 4WD. Four-wheel disc brakes with anti-lock are standard.

Additional features include:
  • Integrated trailer brake controller
  • External auxiliary transmission cooler
  • External engine oil cooler
  • Available 220-amp alternator (150-amp standard)
  • Available dual 220- and 150-amp alternators with Duramax Diesel
  • Dual heavy-duty batteries (720 CCA) are available
  • Available power take-off with Duramax Diesel
  • 3.73 or 4.10 rear axle ratios
  • Wide-track rear axle is available
  • Automatic locking rear axle is available.

2015 Silverado 3500HD Chassis Cab models are assembled in Flint, Mich. – and like all Silverado models, they are backed by the best truck coverage in America:
·         Three-year/36,000 mile limited new vehicle warranty
·         Five-year/100,000 mile limited powertrain warranty
·         Two-year/24,000 mile schedule maintenance coverage, including diesel exhaust fluid.
