Carbon and nutrient cycling in Antarctic landfast sea ice from winter to summer
(Peer reviewed; Journal article, 2023)Seasonal cycling in carbon, alkalinity, and nutrients in landfast sea ice in Hangar Cove, Adelaide Island, West Antarctic Peninsula, were investigated during winter, spring, and summer 2014–2015. Temporal dynamics were ... -
Caught in broad daylight: Topographic constraints of zooplankton depth distributions
(Journal article; Peer reviewed, 2018)For visual predators, sufficient light is critical for prey detection and capture. Because light decays exponentially with depth in aquatic systems, vertical movement has become a widespread strategy among zooplankton for ... -
Coastal ecosystem engineers and their impact on sediment dynamics: Eelgrass–bivalve interactions under wave exposure
(Peer reviewed; Journal article, 2022)Habitat forming ecosystem engineers play critical roles in structuring coastal seascapes. Many ecosystem engineers, such as seagrasses and epifaunal bivalves, are known to have positive effects on sediment stability and ... -
Defining what constitutes a reliable dataset to test for hybridization and introgression in marine zooplankton: Comment on Choquet et al. 2020 “No evidence for hybridization between Calanus finmarchicus and C. glacialis in a subarctic area of sympatry”
(Peer reviewed; Journal article, 2021)The article ‘No evidence for hybridization between Calanus finmarchicus and C. glacialis in a subarctic area of sympatry’ (Choquet et al. 2020) concludes that “no evidence supports a potential for hybridization between C. ... -
Feeding of plankton in turbulent oceans and lakes
(Journal article; Peer reviewed, 2019)Analytical models for the statistical distribution of the gut content of fish larvae in a turbulent ocean environment are compared to data obtained in a field experiment. The proposed model allows the nutrition state and ... -
Impact of ocean acidification and high solar radiation on productivity and species composition of a late summer phytoplankton community of the coastal Western Antarctic Peninsula
(Journal article; Peer reviewed, 2019)The Western Antarctic Peninsula (WAP), one of the most productive regions of the Southern Ocean, is currently undergoing rapid environmental changes such as ocean acidification (OA) and increased daily irradiances from ... -
Nutrient limitation can explain a rapid transition to synchrony in an upwelling-driven diatom community
(Peer reviewed; Journal article, 2022)Identifying the mechanisms controlling the temporal dynamics of ecological communities is key to understand their vulnerability to natural and anthropogenic impacts and to identify early warnings of critical transitions. ... -
A positive temperature-dependent effect of elevated CO<inf>2</inf> on growth and lipid accumulation in the planktonic copepod, Calanus finmarchicus
(Peer reviewed; Journal article, 2022)Calanus finmarchicus were reared from eggs to adults at 12°C and 16°C with non-limiting food in combination with ambient (600 μatm) and high (1100 μatm) pCO2. These conditions are likely to be encountered by the species ... -
Subsurface maxima in buoyant fish eggs indicate vertical velocity shear and spatially limited spawning grounds
(Journal article; Peer reviewed, 2018)Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic (NEA) cod eggs, occasionally deviate from the vertical diffusion‐buoyancy balance by displaying subsurface maxima. Here, we present a ... -
Survival under conditions of variable food availability: Resource utilization and storage in the cold-water coral Lophelia pertusa
(Journal article; Peer reviewed, 2019)Cold‐water coral (CWC) reefs are hotspots of biodiversity and productivity in the deep sea, but their distribution is limited by the availability of food, which undergoes complex local and temporal variability. We studied ... -
Uncertainty sources for measurable ocean carbonate chemistry variables
(Peer reviewed; Journal article, 2023)The ocean carbonate system is critical to monitor because it plays a major role in regulating Earth's climate and marine ecosystems. It is monitored using a variety of measurements, and it is commonly understood that all ... -
Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth
(Peer reviewed; Journal article, 2023)Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The underpinning mechanisms are, however, poorly understood. We use ...
