The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | NOAA RESTORE Science Program: Linking Community and Food-web Approaches to Restoration: Taxonomic data for marsh infauna associated with natural and restored marshes along a salinity gradient generated from a freshwater diversion at West Pointe a la Hache into eastern Barataria Bay, Louisiana, 2018-05-21 to 2021-05-25 (NCEI Accession 0296020) |
| Abstract: | This dataset contains benthic macroinfauna species identifications and number of individuals collected from surface sediment samples at six sites at various distances from a freshwater diversion in the vicinity of West Pointe a la Hache, Lake Hermitage, and Port Sulphur, Louisiana in May of 2018, 2019, and 2021. Five replicates were collected at each marsh location. Taxonomic identification of individuals was determined to the lowest possible taxonomic level. Salinity data and marsh characterization for each sample location are also included in this dataset. Data are in spreadsheet format. |

| Supplementary information: | Sampling occurred at one of three transects established at each site (T.1, T.2, T.3). Sediment samples were collected at two locations at each site (10 and 50 meters from marsh edge) for both natural and restored marshes. Five replicates were collected at each location for a total of ten samples per site on a given sample date. Macroinfauna were collected from the surface sediment with a tulip bulb corer to the approximate depth of 5 centimeters. The sample was placed into a 1-liter jar and preserved with a mixture of 10% formalin and Rose Bengal stain after an initial rinsing through a 500 micrometer sieve. Once the samples were back at the laboratory, each sample was rinsed through a 500 micrometer sieve again with fresh water and placed into a fresh sample jar. This sample was then sorted under a Wild Heerbrugg Stereo Microscope by picking out infauna and placing the specimen into a glass vial of ethanol for identification. The specimens were then identified with a Wild Heerbrugg Stereo Microscope and an Olympus BH-2 Microscope, with accompanying taxonomic literature, and results were recorded.
