Continuing trends of declining bottom-water dissolved oxygen (BWDO) in coastal oceans are a threat to marine organisms, especially the benthos, and in the northern Gulf of Mexico (nGOM), the hypoxic area is expected to expand. Within-sediment vertica

The macrobenthos and megabenthos responses to long-term, recurring hypoxia on the Louisiana continental shelf were compared at four locations with different historical (2000-2010) episodes of annual exposure to bottom-water hypoxia. Measurements of a

As part of a study of the effects of seasonal hypoxia on sediment properties, samples were collected during the spring and late summer of 2009 from four sites of similar sediment type and water depth (30–39 m), but different recent history of botto

Annelid polychaetes are the most abundant marine benthic invertebrates; they play significant functional roles in any aquatic system. Among many roles, their feeding mode promotes transfer of energy to the next trophic level. Polychaetes exhibit five

World wide more than 400 aquatic systems are hypoxic, affecting an area of more than 245,000 square kilometers. The hypoxic area in Gulf of Mexico is the second largest in the world next to the Baltic Sea basin. In the northern Gulf of Mexico hypoxia

The effects of hypoxia on benthic community structure and processes are well documented but the direct and indirect effects of hypoxia on seafloor properties are unknown. Using bottom oxygen data compiled by Louisiana Universities Marine Consortium,

Variation in the spatial and temporal extent of hypoxia in coastal bottom waters of the northern Gulf of Mexico leads to changes in benthic community structure and sediment physical properties. Past and present benthic community structure determines
