The future changes in the physical conditions in the Gulf of Bothnia can have considerable impact on various human activities in the area. In this presentation we concentrate on marine heatwaves and ice conditions. The general changing trends of ice

How will the Gulf of Bothnia be impacted by future climate change? A changing climate will, in addition to warming, reduce the ice-season, change the salinity, sea level, and wave and current conditions. This will in turn have implications for eco sy

It is clear that autonomous underwater vehicles (AUVs) play a pivotal role in the monitoring and exploration of the under-ice environment primarily because they can explore areas that are too dangerous or too costly for manned systems to remain in fo

We studied small scale (50 m to 5 km) sea ice deformation from ship radar images recorded during the N-ICE2015 campaign. The campaign consisted of 4 consecutive drifting ice stations (Floes 1 to 4) north of Svalbard, with a total duration of nearly 5

Ice ridges are the most difficult ice features that ships encounter in first-year ice conditions. Our understanding on ridge resistance on ships is currently limited, but we can assume that the keel of a ridge can have a significant impact to the res

Small scale sea ice deformation was studied in the coastal boundary zone (CBZ). Sequences of coastal radar images from the northern Baltic Sea (13 February to 13 May 2011) were used and trajectories of identifiable objects calculated. Average drift v

Sea ice dynamics is examined for the frequency spectra of ice velocity using mathematical models and ice motion data. The data are from the Baltic Sea and Sea of Okhotsk. A general spectrum for linear coupled ice–ocean free drift is derived and ana

Changes in the mean sea ice thickness and concentration in the Arctic are well known. However, quantitative information about changes in the ice thickness distribution and the composition of the pack ice is lacking. In this paper we determine the ice

Abstract Every operation site, oil and gas drilling, shipping, pipelines and loadingfacilities, need a design basis to be properly planned. Also monitoring of theenvironment when the operation has already started is of utmost importance. This became
