    Description: Bioturbators such as sediment-dwelling marine bivalves are ecosystem engineers that enhance sediment-water exchange and benthic-pelagic coupling. In shallow coastal areas, bivalves are exposed to frequent disturbance and salinity stress that might negatively affect their activity and physiological performance; however, the mechanisms underlying these effects are not fully understood. We investigated the effects of osmotic stress (low and fluctuating salinity) and repeated burrowing on aerobic and contractile capacity of the foot muscle (assessed by the activity of succinate dehydrogenase and myosin ATPase) as well as the levels of organic osmolytes (free amino acids) and biochemical markers of protein synthesis and proteolysis in key osmoregulatory and energy storing tissues (gills and hepatopancreas, respectively) in a common bioturbator, the soft shell clam Mya arenaria. Our findings indicate that exhaustive exercise and osmotic stress interactively affect whole-body protein homeostasis and functional capacity of the foot muscle in soft shell clams which might contribute to reduced burrowing activity of bivalve bioturbators in osmotically challenging environments such as estuaries and shallow coastal zones.

    Effect of salinity stress and burial on Lucine Amino Peptidase in Mya arenaria (2018)
    PANGAEA
    Details
    Publication Date: 2023-02-12
    Description: Bioturbators (such as bivalves, worms, polychaetes), living in a coastal area, experiences frequent changes in salinity. They are often exposed to mechanical disturbances (like wave, currents, storms) forcing them to bury deeper into the sediment to get a better foothold. In nature, these stressors often occurs simultaneously. Osmotic stress negatively affects the burial activity and the physiological performances of soft shell clam, Mya arenaria; however, the mechanism behind this is still unknown. In this dataset we present the combined effect of osmotic stress and repeated burrowing on the activity leucine aminopeptidase in gill tissue and digestive gland of Mya arenaria.

    Vertical profiles of physical and biogeochemical parameters obtained by AWI's AUV "PAUL" during a dive in the vicinity of an ice tongue in the Fram Strait in 2013 (2018)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: AWI's autonomous underwater vehicle "PAUL" covered two 10 km long transects in the Fram Strait on July 2nd / 3rd 2013 to investigate the physical-ecological coupling at an ice edge. The dive was orientated perpendicular to a meltwater front. The meltwater front was associated to a large ice tongue extending from the main ice edge. Every 800 - 1000 m, the vehicle ascended vertically from 50 m water depth to a minimal depth of 3 m to gather a high resolution profile of the following parameters: Temperature, Conductivity, Pressure, Chlorophyll a, CDOM, Dissolved Oxygen, Photosynthetically Active Radiation, and Nitrate. The dataset contains the data of the vertical ascends only. Due to the correction process, which takes into account the pitch angle of the vehicle, pump times, and the position of the respective instrument inside the vehicle, each parameter has an individual depth stamp.
