(2007-09-17)Offatts Bayou is an embayment in the Galveston Bay complex on the upper Texas coast. The bayou is approximately 4.8 km long with a maximum width of 1 km, and an average depth of approximately 5 m. A small created lake (Lake ...
-
(2012-07-16)Coastal low oxygen areas are expanding globally and are predicted to increase in size and duration due to climatic changes associated with a warming ocean. The Gulf of Mexico Hypoxic Zone (GoMHZ) is the second largest ...
-
(2014-01-14)Hypoxic stress is a consequence of the decrease in the oxygen reaching the tissues of the body. The coupling of energy with oxygen makes low tension oxygen sensing and adaptation very essential for survival. The intracellular ...

(2012-07-16)Between July 2009 and October 2011, a new habitat was found for a rarely reported freshwater dinoflagellate species, Thompsodinium intermedium - Comal Springs (Comal County), Texas. In 2011, diel in-situ monitoring in ...

Dissolved Organic Matter Cycling on the Louisiana Shelf: Implications for the Formation of Hypoxia (2012-02-14)Although there has been considerable work on the role of nutrient-derived (mostly nitrate) primary production in fueling hypoxia in northern Gulf of Mexico, very little is known about the relative importance of autochthonous ...
-
(2021-07-20)Since the 1950s, low-oxygen (hypoxic) conditions have developed in the northern Gulf of Mexico (GoM) due to increased nutrient flux from the Mississippi River. Despite the threat hypoxia poses to profitable fisheries and ...
-
(2016-07-20)The Mississippi River drains more than 3 million km2 of the North American continent and discharges 240 million metric tons of sediment and 1.35 million metric tons of nutrients annually into the Gulf of Mexico. This ...
-
(Texas A&M University, 2006-04-12)Oxygen balance is very important and tightly regulated in mammals. Under hypoxia, hypoxia inducible factor 1(HIF-1) dimerizes with hypoxia inducible factor 1± (HIF-) and activates expression of several genes. Using a mammalian ...
-
(Texas A&M University, 2005-02-17)Hypoxia (decreased tissue oxygen levels) has long been considered as a possible mechanism of alcohol-induced developmental deficits, yet research has not conclusively disproved this hypothesis, nor has it provided ...
-
(2016-05-04)During human spaceflight missions, controlled variation of atmospheric pressure and oxygen concentration from a sea-level based normal to hyperoxic levels may occur as part of operational procedure. This activity is of ...
-
(Texas A&M University, 2007-09-17)A study of monomethylmercury (MMHg) concentrations in the water and sediment of the hypoxic zone in the northeastern Gulf of Mexico was conducted on several cruises between April 2004 and May 2005. Surface water MMHg ...
-
(2010-10-12)The Gulf of Mexico hypoxic zone is created by strong persistent water stratification and nutrient loading from the Mississippi River which fuels primary production and bacterial decomposition. The Texas-Louisiana shelf ...
-
(2013-01-03)The Changjiang River provides the main source of sediment and terrestrial derived organic carbon (OC) to the Changjiang large delta-front estuary (LDE) in the East China Sea (ECS). This study analyzed bulk OC, biomarkers ...
-
(2012-02-14)Heparan sulfate proteoglycans modulate many of the growth factor pathways that drive prostate cancer progression. Prior to being secreted into the extracellular matrix, the covalently attached HS chains are modified by ...
-
(2009-06-02)Hypoxia (dissolved oxygen concentrations less than 1.4 ml/l) is a recurrent seasonal phenomenon on the Louisiana Shelf, caused by the combined effects of nutrient loading by the Mississippi and Atchafalaya River System ...
-
(2014-08-06)The Mississippi-Atchafalaya river system discharges into the northern Gulf of Mexico and peaks during the spring freshet bringing high levels of nutrients that spur eutrophication in surface waters, often resulting in ...
-
(2009-05-15)Here we studied the role of hypoxia and hypoxia-induced factors in the development of breast cancer brain metastasis by using ENU1564, a carcinogen-induced mammary adenocarcinoma cell line. We detected hypoxia noninvasively ...
-
(2013-12-02)I examine the vertical structure of water-column stability and its relationship to near-bottom dissolved oxygen (DO) concentration in the hypoxic zone of the Texas-Louisiana Shelf using observations collected between year ...
-
(Texas A&M University, 2004-11-15)Bottom water hypoxia and its influence on the environment have been topics of increasing concern for many coastal regions. This research addresses both spatial and temporal variability in sediment biogeochemistry at the ...
-
(2014-05-07)In Oso Bay, a wastewater treatment plant acts as a source of eutrophication and may have measureable impact on the health of the bay. The objectives of this study were to create a model for modeling dissolved oxygen ...
