These objectives were to allow an understanding of the interaction between whelk, a commercially important species, and the anticipated changes in marine heatwaves and sea bottom temperature for the present (2003 - 2022), near (2040 - 2059) and far - future (2079 - 2098) period. Two data collection methods were employed for each respective component, including simulating marine heatwaves of different intensities and durations in aquaria to assess mortality, righting time and behaviour of whelk. The latter part of the project required collecting stable isotope data from whelk shells from three sites (Shetland, Nefyn and Jersey), varying over a latitudinal gradient. Temperature profiles for individual whelk were produced and analysed.

Data obtained from aquarium-based experiments and laboratory processes. false To understand biological responses of whelk to marine heatwaves, whelk were divided into four separate, temperature – controlled systems in an aquaria, such as 40 whelk experienced one of four heatwave scenarios, varying in intensity and duration. Eighty whelk remained in the control system, where no heatwave was simulated. The experiments were repeated three times with new whelk for each iteration. Data for behaviour were collected through taking daily photographs and assigning behaviours which were then compared between scenarios. Righting experiments were conducted multiple times throughout the three experimental replicates. Mortalities were noted. Full details can be read on the metadata form “Understanding the biological responses of the common whelk, Buccinum undatum, to marine heatwaves scenarios simulated in an aquarium setting”. To understand the interaction of temperature and whelk in their natural environment and between locations, whelk shells were drilled using specialised drill bit and cleaning protocol. Samples were processed at British Geological Survey (BGS), using mass spectrometry to calculate stable isotope δ18O values for each drilled shell sample (δ18Os). Temperature estimations were derived from isotope values using a paleotemperature equation and site-specific water isotope values (δ18Ow) (Hollyman et al., 2020). Temperature profiles were then reconstructed using hourly sea bottom temperature (SBT) data. Growth rates were calculated and compared between locations.
