Sampling is carried out bi-monthly on the R/V Walton Smith (University of Miami) as part of the South Florida Program (NOAA Atlantic Oceanographic and Meteorological Laboratory/ AOML) and the Marine Biodiversity Observation Network (MBON). Samples are collected at three stations: Molasses Reef (25.051638 N, 280.22858 W), Looe Key (24.323028 N, 281.248068 W), and Western Sambo (24.286048 N, 281.428898 W). At each station, horizontal hauls (surface water) are performed with 64, 200, and 500 mm mesh size Bongo plankton nets. Each net tow is carried out for 5 min at 1 knot. The three size classes are split using a Folsom plankton splitter and preserved with 15 % formalin for morphological analysis. Morphological identification follow the protocols of the International Council for the Exploration of the Sea (ICES) (Roger et al. 2000) targeting a minimum count of 200 animals per sample. For the 64 and 200 mm net tows, a 5–10 mL aliquot is subsampled after resuspension of 300 ml of the original zooplankton sample using a Stempel pipette. Zooplankton are then identified and counted using a microscope. Zooplankton are identified to the lowest taxonomic level possible. Zooplankton abundances (density; individuals m-3) are calculated by dividing animal counts by the product of net mouth area, tow speed, and tow duration (i.e., volume of water filtered by the net). Abundances of gastropods, the copepod order Harpacticoida, and the genera Paracalanus and Oithona are converted to biomass after Kelble et al. (2010).
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 192 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.
