Abstract Snow and ice topography impact and are impacted by fluxes of mass, energy, and momentum in Arctic sea ice. We measured the topography on approximately a 0.5 km2 drifting parcel of Arctic sea ice on 42 separate days from 18 October 2019 to 9

Contrasting glacial meltwater effects on post-bloom phytoplankton on temporal and spatial scales in Kongsfjorden, Spitsbergen

Autor: Willem H. van de Poll, Gemma Kulk, Patrick D. Rozema, Corina P. D. Brussaard, Ronald J. W. Visser, Anita G. J. Buma

Publikováno v: Elementa: Science of the Anthropocene, Vol 6, Iss 1 (2018)

Glacial meltwater discharge in fjords on the west coast of Spitsbergen is increasing due to climate change. The influence of this discharge on phytoplankton nutrient limitation, composition, productivity and photophysiology was investigated in centra

Solar radiation and solar radiation driven cycles in warming and freshwater discharge control seasonal and inter‐annual phytoplankton chlorophyllaand taxonomic composition in a high Arctic fjord (Kongsfjorden, Spitsbergen)

Fjords on the west coast of Spitsbergen experience variable Arctic and Atlantic climate signals that drive seasonal and inter‐annual variability of phytoplankton productivity and composition, by mechanisms that are not fully resolved. To this end,

Annual patterns in phytoplankton phenology in Antarctic coastal waters explained by environmental drivers

Publikováno v: Limnology and Oceanography, 65(7), 1651-1668. Wiley-Blackwell

Coastal zones of Antarctica harbor rich but highly variable phytoplankton communities. The mechanisms that control the dynamics of these communities are not well defined. Here we elucidate the mechanisms that drive seasonal species succession, based

Viruses are a major source of mortality for phytoplankton and bacteria and are therefore seen as drivers of food web dynamics and biogeochemical cycling in the marine pelagic environment. Previous studies have shown that aquatic viruses adsorb to sus

Effects of prolonged darkness on Arctic phytoplankton composition were investigated with lab experiments and a pigment time series in Kongsfjorden, Spitsbergen (78°55′N). Chlorophyll a (Chl a), pigment composition, particulate organic carbon, cell

The pigment composition of Phaeocystis antarctica (Haptophyceae) under varius conditions of light, temperature, salinity, and iron

Autor: Jacqueline Stefels, Maria A. van Leeuwe, Ronald J. W. Visser

Publikováno v: Journal of Phycology, 50(6), 1070-1080. Wiley

The pigment composition of Phaeocystis antarctica was monitored under various conditions of light, temperature, salinity, and iron. 19'-Hexanoyloxyfucoxanthin (Hex-fuco) always constituted the major light-harvesting pigment, with remarkably stable ra

Low nutrient availability reduces high-irradiance-induced viability loss in oceanic phytoplankton

Autor: Ronald J. W. Visser, Anita G. J. Buma, Gemma Kulk, Willem H. van de Poll

Publikováno v: Limnology and Oceanography, 58(5), 1747-1760. Wiley-Blackwell

In situ viability of oceanic phytoplankton may be relatively low in open oceans. This is assumed to be related to the high-irradiance and low-nutrient conditions typical for oligotrophic regions. However, experimental evidence for this phenomenon was
