The Northern Baltic Proper is a splitting area of the Baltic Seasaline water route towards the two terminal basins - the Gulfof Finland and the Western Gotland Basin. Large halocline variations(vertical isopycnal displacements of more than 20 m, intr

We present four case studies of exceptional wave events of meteorological origin, observed on the Finnish coast in the summers of 2010 and 2011. Eyewitnesses report unusually rapid and strong sea-level variations (up to 1 m in 5–15 min) and strong

Operational marine environmental modelling has been considered notoriously difficult; consequently there are very few operational models of the marine environment. Operational modelling of harmful algal blooms (HABs) requires the modelling of individ

This work introduces a novel approach for the modelling and coupling of sea ice biology to sea ice physics. The central concept of the coupling is the definition of the Biologically Active Layer, which is the time-varying fraction of sea ice that is

A method is presented for the evaluation of the exhaust emissions of marine traffic, based on the messages provided by the Automatic Identification System (AIS), which enable the identification and location determination of ships. The use of the AIS

Intrusions observed in the regions of intense mesoscale eddies of the Baltic Sea are studied. The study is based on the data of the closely spaced CTD profilings performed in the Eastern Gotland Basin after the major inflow of 1993. The results obtai

Data from closely spaced CTD profiling performed in the eastern Gotland Basin after the 1993 inflow event are used to study thermohaline intrusions in the Baltic Sea. Two CTD cross sections display abundant intrusive layers in the permanent halocline

Global algorithms for chlorophyll‐a (chl‐a) concentration and primary productivity retrieval from satellite observations are often not applicable to areas that are turbid and rich in coloured dissolved organic matter (CDOM), such as the Baltic Se

The onset of the vernal phytoplankton bloom in heterogeneous convection at a temperature below the temperature of maximum density ( θ ρ ) is studied by means of an idealized numerical model. The modeled setting resembles the well-documented conditi

The effect of upwelling on the preconditions for noxious cyanobacterial blooms in a nitrogen-limited estuary is studied with Nodularia blooms in the Gulf of Finland especially in mind. An idealised physical–chemical model is derived and integrated.
