description: Measurements of transmitted solar radiation under sea ice have been performed on First-Year-Ice (FYI) and Multi-Year-Ice (MYI) during the ALERT2018 campaign (Multidisciplinary Arctic Program (MAP) - Last Ice) off Alert, Nunavut, Canada in the Lincoln Sea between 07 May and 23 May 2018. The radiation measurements have been performed with Ramses spectral radiometes (TriOS, Rastede, Germany). All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). The irradiance sensor (cos-collector) for energy budget calculations was installed on the ROV. All times are given in UTC.

description: Gut fluorescent content of dominant copepods was measured according to the method described by Mackas and Bohrer (1976; doi:10.1016/0022-0981(76)90077-0) and modified by Morales et al. (Estimates of ingestion in copepod assemblages: gut fluorescence in relation to body size. In: Trophic Relationships in the Marine Environment. Proceedings of the 24th European Marine Biology Symposium, pp. 565-577. Edited by M. Barnes, and R.N. Gibson. Aberdeen University1990). Deep-frozen samples of mesozooplankton were used for measurements of gut fluorescence of copepods. Gut evacuation rate was calculated according to Dam and Peterson (1988; doi:10.1016/0022-0981(88)90105-0). Ingestion rates were estimated by applying gut clearance rate to gut pigment contents. Turner Fluorimeter was used for measurements of copepod gut fluorescence.

title: Mesozooplankton average length during Akademik Kovalevsky cruise AK7/4, Part I

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 0.145 mm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

title: Experiment on the response of the sea star Asterias rubens to heat stress and ocean acidification: experiment 1: feeding rate, respiration rate and scope for growth

description: Robust estimates of marine species vulnerability to ongoing climate change require realistic stressor experiments. Here, we subjected an important coastal predator, the sea star Asterias rubens, to projected warming and ocean acidification over an annual seasonal cycle. Warming and, less so, acidification, had strongly season-specific impacts on animal energy budgets. Specifically, simulated future summer temperatures caused &gt;95% sea star mortality, reduced feeding rate and body mass loss. Additional acute experiments demonstrated that respiratory oxygen flux was preferentially directed to support high summer metabolism at the expense of feeding-related processes. Using 15 years of field temperature data and end of century warming projections, we estimate that potentially lethal summer heat waves will occur in 20% of future years. Our study demonstrates the importance of assessing stress responses along seasonal thermal cycles and the high selective force that future summer heat waves likely can exert on coastal marine animal populations.

title: Effects of artifical light at night (ALAN) on three benthic grazer species (Arbacia lixula, Paracentrotus lividus, Cerithium spp.) from the Adriatic Sea (June - August 2021): time-lapse experiment 1

description: This data set shows the day-/night feeding behaviour of Arbacia lixula, Cerithium spp. and Paracentrotus lividus under artificial light at night (ALAN), derived from time-lapse photography, with acclimation.
