16-664: The Natalbany River drains into Lake Maurepas in Louisiana in the United States . It is about 79.5 miles (127.9 km) long. It is speculated that the name of the river is derived from the Choctaw words nita meaning bear and abani which means "to cook over a fire" in the Choctaw language . Lake Maurepas Lake Maurepas was named for Jean-Frédéric Phélypeaux , comte de Maurepas , an eighteenth-century French statesman , and chief adviser to King Louis XVI . Jean-Frédéric

32-515: Is approximately 0.15 m (6 in). However, greater tidal amplitude is associated with meteorological events (i.e. winds) that influence both Lake Pontchartrain and Lake Maurepas. That results in interesting patterns of tidal exchange and, presumably, in situ mixing on weekly and fortnightly time scales. The salinity of the lake is directly influenced by exchange with Lake Pontchartrain. The salinity of Lake Maurepas ranges between 0 and 3 parts per thousand (Day et al., 2004). Typically, salinity

48-467: Is higher along the eastern shore, near Pass Manchac. Due to Lake Maurepas’s shallow depth, even relatively low energy wave action results in sediment resuspension and, therefore, relatively high turbidity and low transparency, which influences the degree to which primary production can occur in the water column and benthos . The Maurepas Swamp Wildlife Management Area (WMA) is located approximately 25 miles (40 km) north-west of New Orleans, along

64-671: Is selling gases and chemicals for industrial use. Air Products is headquartered in Trexlertown, Pennsylvania , in the Lehigh Valley region of eastern Pennsylvania . As of 2024, Air Products is the fifth-largest employer in the Lehigh Valley. Air Products was founded in Detroit in 1940 by Leonard Parker Pool with the objective of establishing on-site production and sales of various forms of industrial gas . The following year, in 1941,

80-469: The Natalbany River . The average freshwater input to Lake Maurepas from these rivers and other minor terrestrial sources is less than 3,400 cubic feet per second (96 m /s) (CWPPRA Environmental Workgroup, 2001). To the north-east, Lake Maurepas is connected to Lake Pontchartrain by Pass Manchac (comprising South Pass and the smaller North Pass). The land between the two passes forms Jones Island, and

96-403: The U.S. entered World War II , and Air Products began manufacturing mobile generators for the production of oxygen used in high elevation military flights and necessary to meet the needs of the U.S. Air Force and allied air forces. In 1944, the company relocated its headquarters from Detroit to Chattanooga, Tennessee , where it expanded its oxygen production manufacturing capacity to meet

112-584: The WateReuse Association for Outstanding Water Conservation Efforts for conserving 62 million US gallons (230,000 m ) of drinking water annually by converting to recycled water for the cooling process at its Santa Clara, California manufacturing facility. The award was presented during the 25th Annual WateReuse Symposium. WRA recognizes projects that have advanced the acceptance of water reuse through education, sound science, and technology using reclamation, recycling , reuse, or desalination for

128-622: The benefit of the public and the environment. Air Products provided the liquid hydrogen and liquid oxygen fuel for the Space Shuttle external tank . Air Products has had a working relationship with NASA for five decades, supplying the liquid hydrogen used for every Space Shuttle launch and the Mercury and Apollo missions. Air Products is included on the Dow Jones Sustainability North America Index as one of

144-430: The best performing sustainable companies for the period of 2008 to 2011. In January 2004, Air Products (NYSE: APD) was named a Maplecroft Climate Innovation Indexes (CIIs) Leader, the 17th largest U.S.-based company that has undergone evaluation of its climate-related innovation and carbon management programs. Air Products is currently working on several preeminent carbon capture and storage demonstration projects around

160-988: The needs of the U.S. military and its allies in their war against Nazi Germany and the Axis powers . Following the end of World War II , the company relocated its headquarters and operations to Emmaus, Pennsylvania in the manufacturing-intensive Lehigh Valley region of eastern Pennsylvania . In the late 1950s, it completed the development of its current corporate headquarters in neighboring Trexlertown . Air Products serves customers in technology, energy, healthcare, food, and industrial markets worldwide with atmospheric industrial gases, including oxygen, nitrogen , argon , hydrogen , and carbon dioxide , process and specialty gases, performance materials, and chemical intermediates. Air Products produces refinery hydrogen , liquified natural gas technologies and equipment, epoxy additives, gas cabinets , advanced coatings, and adhesives . In 2001, Air Products Received an Award of Merit from

176-491: The passes converge on the eastern side of the island into one unified Pass Manchac. Tidal exchange with Lake Pontchartrain through Pass Manchac is a more significant influence on Lake Maurepas’s volume and elevation than tributary freshwater discharge. The Manchac Swamp Bridge , which carries Interstate 55 , traverses the narrow strip of land between lakes Maurepas and Pontchartrain. The mean astronomical tide in Lake Maurepas

192-653: The south shore, as well as south of Lake Maurepas. The area is north of LaPlace and extends towards Sorrento . Initially, the Richard King Mellon Foundation donated 61,633 acres (249.42 km ) to the Louisiana Department of Wildlife and Fisheries (LDWF) for the Maurepas Swamp WMA . Subsequent acquisitions and donations have brought the total to 122,098 acres (494.11 km ). The Louisiana Department of Wildlife & Fisheries has noted that

208-462: The swamp would benefit from "cooperative freshwater reintroduction projects designed to revive the swamp, and improved control of invasive plant species that have overtaken much of this important and scenic swamp." Lake Maurepas is a site for a proposed carbon sequestration project by Occidental Petroleum and Air Products . Air Products Air Products and Chemicals, Inc. is an American international corporation whose principal business

224-764: The world. In 2010, Air Products was awarded the Rushlight Hydrogen and Fuel Cells industry award for the Series 10 hydrogen fuelling station, which celebrates the leading environmental technologies and innovations by organizations throughout the United Kingdom and Ireland by promoting development in hydrogen and fuel cells and enabling further development and funding to be granted toward reducing carbon emissions. In March 2010, Corporate Responsibility magazine named Air Products to its 100 Best Corporate Citizens List. In 2013, Air Products' high purity built-in purifier argon
