©2020 Biological and Chemical Oceanography Data Management Office.This dataset describes the muscle mercury concentrations of individuals of three fish species (Red Drum Sciaenops ocellatus, Southern Flounder Paralichthys lethostigma, and Atlantic Croaker Micropogonias undulatus) in the Matagorda Bay region of Texas in the northwestern Gulf of Mexico.
Fish collection locations and associated information are found in an accompanying dataset for this project: https://www.bco-dmo.org/dataset/916418.
Muscle samples from individual fish were dissected, dried, and pulverized to a fine powder. Powdered muscle samples were analyzed at the SUNY College of Environmental Science and Forestry. Samples are weighed into boats and placed in an autosampler. The autosampler places the boat into a furnace to undergo thermal decomposition under oxygen. A catalyst furnace then removes interferences and reduces all mercury species. The mercury is subsequently trapped on a gold amalgamator, then desorbed and swept into an atomic absorbance spectrophotometer equipped with a 254-nanometer (nm) mercury lamp.
