The impacts of schooling mesopredators (smaller sharks and rays that are prey to large sharks) on benthic shellfish communities has become a strong concern for natural resource...

Wastewater treatment plants (WTP) input large amounts of effluent into coastal and estuarine waters. These effluents contain high concentrations of nutrients and microbes. These...

We assessed short-term ecological and potential human health effects of wastewater treatment plant (WTP) effluent by measuring δ15N‰ and microbial concentrations in oysters and...

The removal of fish biomass by extensive commercial and recreational fishing has been hypothesized to drastically alter the strength of trophic linkages among adjacent habitats....

The Dr. John Valentine Lab at the Dauphin Island Sea Lab reports the findings of a three year study conducted in the upper reaches of the Mobile Bay Estuary and the lower Mobile...

In May 2006 the Powers Fisheries Ecology Lab in collaboration with National Marine Fisheries Service initiated a nearshore longline survey to investigate the abundance and...

While numerous studies have noted the potential for cascading impacts resulting from piscivorous fish depletion from coral reef food webs (Jackson 2001, Jackson et al. 2001,...

In addition to the multimillion dollar US fishery they support, oyster reefs are a critical component of healthy estuaries fulfilling several key ecological functions. Their...

From July-September, 2004, time series data were collected from a stationary mooring located off the coast of Fairhope, Alabama. The data collected include pressure,...

A transect was sampled from Mobile Bay, Alabama to 40 km offshore at monthly to bi-monthly intervals from March, 2007. Horizontal salinity gradients ranged from 8 to 18 PSU in...

This dataset contains transect data from two research cruises to the Ross Sea, Antarctica, aboard the RV Nathaniel B. Palmer (NBP) in December 2004 to January 2005 (NBP04-09)...

In 2004 Compass Port LLC (Compass Port) and the Dauphin Island Sea lab (DISL) developed a research plan to assess the possible biological impacts of the proposed Compass Port...

The Alabama Oyster Reef Restoration Program began in 2004 to experimentally assess ecosystem benefits of oyster reef restoration in marsh creeks in Mobile Bay, AL, USA, and...

The objectives of study are to determine the extent to which the presence of Myriophyllum spicatum has altered community structure and the intensity of predator-prey...

Salt marshes provide ecosystem services that include critical habitat for commercially important crustaceans and fish, and energy export to adjacent estuarine habitats. The goal...

Dissolved oxygen data from field experiments conducted in three lagoonal environments in Perdido Bay, Florida, on a bimonthly basis since December 2001. For each experiment,...

As part of a comparison of benthic metabolic rates between bottom types (bare sediment vs. with seagrass patches) within and across three lagoonal environments in Perdido Bay,...

Nutrients and water quality have been measured in three lagoonal environments in Perdido Bay, Florida, since Dec 2000. The data include dissolved inorganic nitrogen, dissolved...

Basic hydrographic data have been collected from three lagoonal environments in Perdido Bay, Florida, since Sept 2000. The data include salinity, temperature, dissolved oxygen,...
