Gulf of Mexico - an overview | ScienceDirect Topics
The Gulf of Mexico (GoM) is defined as a distinct marine region characterized by high biodiversity, influenced by tropical waters and a significant river system, particularly the Mississippi River, making it a unique biogeographic ecoregion with rich pelagic fauna.
The Gulf of Mexico - ScienceDirect
The Gulf of Mexico (GOM) is a marginal sea of the Atlantic Ocean bordered by five states of the United States on the northern and the eastern border, five Mexican states on its western and southern border, and Cuba to the southeast (Fig. 18.1). The GOM is ninth, fifth, and ninth among oceans and semienclosed seas in terms of its area (1,507,639 km 2), average depth (1615 m), and volume ...
Climatic and anthropogenic controls on late Holocene sediment transport ...
These workers also used zircon U-Pb ages from late Pleistocene sands from the Gulf of Mexico to show enhanced sediment supply from the Missouri and Upper Mississippi tributaries that was linked to ice stream activity, and increased transport capacity during deglacial melt-water floods.
Spatiotemporal dynamics of coastal dead zones in the Gulf of Mexico ...
The analysis revealed that dead zones in the Gulf peaked in 2009 (17,699 ± 679 km2) and contracted afterward in terms of both size and persistence (% days with hypoxia). Despite this contraction, the average size between 2010 and 2019 was twice that of the coastal reduction goal (< 5000 km 2) set by the Gulf of Mexico Hypoxia Task Force.
Response of Deep-Sea benthic foraminiferal faunas to the 2010 BP ...
Patterns in Gulf of Mexico benthic foraminiferal assemblages during the DWH spill were identified and their potential use as indicators of past oil spills was investigated. Wall composition, assemblage composition and species diversity were analyzed and compared to levels of dark particulate matter (DPM) concentrations in core DSH 10.
Controls on fluid discharge at cold seep-hydrate systems: 4D seismic ...
Instead, these mechanisms are primarily influenced by processes within the deeper geological structure, which in the Gulf of Mexico is strongly controlled by salt tectonics and in Cascadia by plate convergence. This study significantly advances our understanding of the factors controlling methane discharge at deep-sourced cold seep/hydrate systems.
Geochemistry and mineralogy of beach sediments in the northern Gulf of ...
Abstract Geochemical and mineralogical studies were performed in the La Pesca (LP) and Tesoro Altamira (TA) beach sediments, located in the Tamaulipas state, northern Gulf of Mexico. The main aim of this study is to infer the weathering history and provenance and to discriminate the tectonic environment of the beach sediments. The sediments are composed of quartz with small amounts of ...
Structure, age, and tectonic evolution of the Gulf of Mexico
The Gulf of Mexico is an isolated oceanic basin whose nature, structure and age are not fully elucidated, mostly because seafloor spreading isochrons have not been identified in this basin so far. We compiled and processed all publicly available marine magnetic data to produce a new magnetic anomaly map of the Gulf of Mexico.
Hypoxia in the Gulf of Mexico: A machine learning approach for ...
Hypoxia in the Gulf of Mexico poses a multifaced environmental issue marked by seasonal fluctuations, spatial variability, and considerable impacts on marine ecosystems. This study utilizes field and remote sensing data to develop machine learning models that classify hypoxic patches in the northern and eastern Gulf of Mexico.
Mangrove forests in a rapidly changing world: Global change impacts and ...
The Gulf of Mexico is a valuable region for advancing understanding of global change impacts to mangrove forests because, in addition to a rich legacy of ecological research, coastal wetlands in the region are abundant and span multiple ecologically-relevant abiotic gradients (López-Portillo and Ezcurra, 2002; Méndez-Alonzo et al., 2008; Day et al., 2013; Yáñez-Arancibia et al., 2014 ...
