Benthic habitats of Marra Sea Country - Gulf of Carpentaria, Australia (2021)

Brief description

This dataset summarises benthic surveys in Marra Sea Country, including the Limmen Marine Park (Commonwealth) and Limmen Bight Marine Park (Northern Territory). Records are from 3 datasets as described by the investigators are (1) A point (site) shapefile describes (a) seagrass presence/absence, (b) seagrass species composition, (c) algae cover and (d) benthic macro-invertebrate cover at n=2018 sites surveyed by small vessel and helicopter. (2) A point (site) shapefile describes deep-water (a) seagrass presence/absence, (b) seagrass species composition, (c) algae cover and (d) benthic macro-invertebrate cover at 54 sites surveyed by benthic towed camera and sled net. (3) The meadow shapefile describes attributes of 69 seagrass meadows. Data sourced from cited paper on 2020-06-01. The sampling methods used to study, describe and monitor seagrass meadows were developed by the TropWATER Seagrass Group and tailored to the location and habitat surveyed; these are described in detail in the relevant publications (https://research.jcu.edu.au/tropwater).
