title: Blue carbon data for marine invertebrates living on soft substrata (20m South Cove and Hangar Cove) and Rocky substrata (Cheshire Island) around Rothera Point Antarctica (2013-2015).

description: Blue carbon data for assemblages living on soft substrata (20m South Cove and Hangar Cove) and Rocky substrata (Cheshire Island) around Rothera Point Antarctica (2013-2015) in both winter and summer. All fauna larger than 1mm (soft substrata) and 3mm (hard substrata) were collected by suction samplers. All fauna were identified and then carbon values calculated for each species from dry mass and ash free dry mass.
description: Data was collected from the shoreline surrounding Rothera Point from depths of from 6, 12 and 20m from rocky substrata and 20m on the soft substrata. Suction samplers were used on both the rocky and soft substrata. The data are the biomass data for each species (with its functional group) for each square meter for each of the samples. Please find below some specific precisions for each type of substrata. **Rocky shore mass data** 4 CSV files for winter and summer ash mass (skeletal mass) and biomass (AFDM). g m-2. - Rocky_shore_winter_organic_mass.csv Rocky shore winter organic mass (m-2) from Cheshire Island, 6,12 and 20m depth. - Rocky_shore_summer_organic_mass.csv Rocky shore summer organic mass (m-2) from Cheshire Island, 6,12 and 20m depth. - Rocky_shore_winter_skeletal_mass.csv Rocky shore winter skeletal mass (m-2) from Cheshire Island, 6,12 and 20m depth. - Rocky_shore_summer_skeletal_mass.csv Rocky shore summer skeletal mass (m-2) from Cheshire Island, 6,12 and 20m depth Here are the functional groups for each species Code, Functional Group SP, Pioneer sessile suspension SC, Climax sessile suspension SS, sedentary suspension SM, mobile suspension DC, deposit feeding crawlers DV, deposit feeding sedentary (soft) DS, deposit feeding sedentary (hard / shelled) GC, grazer PS, scavenger/ predator - sessile soft PC, scavenger/ predator - sessile hard / shelled PM, scavenger/ predator - mobile soft PL, scavenger/ predator - mobile hard / shelled PA, scavenger/ predator - arthropod Auto, autotrophic Parasite, parasites Flexible, Flexible The name of each row is given following this nomenclature: T161 = transect 1, 6m depth, 1st replicate For rocky samples, data was collected from the shoreline surrounding Rothera Point from depths of from 6, 12 and 20m **C mass 20m soft hard substrata ** 2 files of soft substratum C mass data. - 20m_soft_substrata_organic_carbon.csv is the soft substratum organic carbon mass (m-2) from both South Cove and Hangar Cove at 20m - 20m_soft_substrata_skeletal_carbon.csv is the soft substratum skeletal carbon mass (m-2) from both South Cove and Hangar Cove at 20m Biomass and skeletal g C m-2 for the same functional groupings. Both South Cove, Hangar Cove, winter and summer. The naming convention for the samples is T1201W is T1=transect 1 (or 2 or 3); 6, 12 or 20 =depth; 1,2 or 3 = replicate number; S,W = summer or winter. Those descriptors appear in the last columns, transect, depth, replicate, season and then 'Site' is the name repeated from the first column.
