Since the early 20th century hydrographic measurements have been carried out in the ArcticOcean. Although today the Arctic is a hotspot of climate change, data sampling is still sparse due to the large sea [...] climate studies in the ArcticOcean. Many of the collected data are publicly available, but scattered across different electronic archives. Consequently, scientists working on Arctic climate change have to [...] awi.de The „Unified Database for Arctic and Subarctic Hydrography“ (UDASH) is an attempt to gather all publicly available temperature and salinity data for the ArcticOcean and to provide them on a high quality

But I am currently focusing more on BGC modelling in the framework of the H2020-Project COMFORT and the BMBF nuArctic projects. nuArctic investigates nutrient [...] examined the decadal variability of the carbon cycle in the Indian Ocean region. For the Ph.D. I am doing Ocean Biogeochemical Modeling for Ocean Alkalinity Enhancement in deep and bottom water formation regions [...] studied marine sciences and have worked with global ocean biogeochemistry models as well as observations in the past. I am interested in understanding ocean carbon cycling and its interactions with climate

My study areas are the Lena Delta and Bykovsky Peninsula in Siberia, and a transect from Teshekpuk [...] Global warming will continue to warm the Arctic resulting in the degradation of permafrost soils. This leads to large-scale ground subsidence. Vast regions of the Arctic are covered with ice-rich silts containing
questions of my research. My particular interest focuses on species interactions in temperate and Arctic regions and on the effects alien marine organisms on native coastal ecosystems. Mathias Wegner Parasites [...] on transgenerational plasticity (parental environment effects on offspring traits) in response to ocean warming. So far, I can say that maternal effects play an important role in populations’ adaptive responses

Shorter shipping distances entail substantial fuel savings. However, decisions on whether or not to switch from more traditional shipping routes to the Arctic will still need

A region in which new seafloor continuously forms is, for instance, Gakkel Ridge in the Arctic. This is a submarine mountain range whose northern foothills extend from the northeast tip of Greenland
