Beginning in late 1979, the Alabama Coastal Area Board (CAB) funded a series of baseline surveys on the coastal resources of Alabama, from which they could develop a monitoring program to observe any significant changes in the resources over time. Eight stations within Mobile Bay, Alabama were sampled monthly from April 1980 to April 1981. Data collected included samples for benthic fauna, pelagic fauna, sediment particle size, total organic carbon, foraminifera, zooplankton, phytoplankton, chlorophyll, turbidity, river flow, and hydrographic parameters. The subset of data presented here are for the benthic fauna, which were sampled by 0.1 m^2 Peterson grab. Fauna were enumerated and identified to the lowest taxon possible, and mainly included crustaceans, molluscs, polychaetes, and echinoderms. Data in readily accessible digital form are available from April 1980 to February 1981.

Data are available from April 1980 to April 1981 for eight stations (14 sampling trips), and one station until August 1981 (4 additional trips).

This dataset contains physical, chemical, and biological data collected during ten years of near-monthly shipboard surveys carried out in Mobile Bay between May 1989 and December 1999. Station locations ranged from the Mobile River delta to the mouth of Mobile Bay, from Bon Secour to the eastern part of Mississippi Sound, and outside Mobile Bay in the northern Gulf of Mexico. Hydrographic profiles and water samples were collected at each station.

This GIS layer provides the location where samples were taken in a survey conducted by D. Franz (1976)

Using version 52.30 of the ADvanced CIRCulation (ADCIRC) numerical model (Luettich and others, 1992), astronomic tides were simulated at Mobile Bay, Alabama (AL), under scenarios of Holocene geomorphic configurations representing the period of 3500 to 2300 years before present including a breach in the Morgan Peninsula and a land bridge at Pass aux Herons, as described in Smith and others (2020). The two-dimensional ADCIRC model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and transport scenarios. For this study, the ADCIRC unstructured finite element mesh domain spans to the 60th meridian west in the Atlantic Ocean and has higher spatial resolution elements (20 - 100 meters (m)) along the northern Gulf of Mexico coast from Louisiana through the Florida Panhandle. The ADCIRC model setup requires the input of topographic and bathymetric elevations at each mesh node. Model inputs in the form of topography and bathymetry and model outputs in the form of water levels and velocities at each mesh node are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Smith and others (2020).

These three tapes contain Ichthyoplankton data from the BLM/OCS South Texas Program. The data were collected from December 1974 to September 1975 on the R/V Longhorn. The data were submitted by Dr. John H. Finucane from National Marine Fisheries Service (NMFS) in Panama city. This project was supported by contract no. AA550-CT6-17, Inter-agency no. 08550-IAS-19. These data used to be under accession numbers 7800506 and 7800032 but were never processed. They have now been consolidated under one accession number 9000183 and are available in F124-Zooplankton file format of NODC.
