Measurements for a 92 day climate manipulation experiment on replicate macrofaunal mesocosms collected on the cruise JR18006 in the Western Barents Sea and at Rothera research station in 2019

Measurements were collected during the 92 day lab-based experiment carried out on replicate macrofaunal mesocosms of Astarte crenata, Ctenodiscus crispatus, Cistenides hyperborea from the Western Barents Sea and Aequiyoldia eightsi and Laternula elliptica from Rothera Point, Antarctic Peninsula. Macrofauna were collected on cruise JR18006 in the Western Barents Sea and by hand during scuba dives in the cove adjacent to Rothera research station. Experimental measurements include carbonate chemistry indices measured in water samples; carbon dioxide concentration levels; benthic invertebrate response rate, burial rate, sediment particle reworking, bioirrigation, and associated nutrient concentrations; benthic invertebrate body size and individual biomass; sediment organic material content, and sediment particle size.

Supported by the INSPIRE Doctoral Training Partnership programme (grant NE/S007210/1) and ''The Changing Arctic Ocean Seafloor (ChAOS) - how changing sea ice conditions impact biological communities, biogeochemical processes and ecosystems'' project (NE/N015894/1 and NE/P006426/1, 2017/2021), Natural Environment Research Council (NERC) in the UK.

Statement

Standard protocols were followed and data entry double checked by independent person. Missing values for behavioural activity (response rate, burial rate) relate to the individual not completing the associated activity within the 60 minute timeframe. Missing biomass data is due to mortalities. Original unedited raw videos and processed, stitched together timelapses are provided. Original unedited raw fSPI images and processed, stitched together fSPI profiles are provided.

3 replicate water samples were taken for each independent treatment level in the experiments. Standards and blanks were utilised when analysing total alkalinity as per the HCl protocol. Standard protocols were followed and data entry double checked by independent person.

LiCOR instruments were calibrated 3 months prior to the start of the experimental period.
