Baltic sea level low-frequency variability

Low-frequency Atlantic sea level variability

The control run of the Hadley Centre-coupled climate model (HadCM3) is used to establish the sources of multidecadal/ centennial sea level (SL) variations in the northwest Atlantic. It is shown that variations in the sea level for the largest part of this area are related to variations in the thermohaline structure of the upper (c 500 m) part of the ocean. Temperature variations dominate steric...

Modelling sea level variability in different climates of the Baltic Sea

Within the Baltic Sea Region INTERREG IIIB project `Sea level change affecting the spatial development in the Baltic Sea region' (SEAREG, 2002-2005) sea levels in past and future climate were investigated based upon 6-hourly regional model results. The main factors affecting the longterm mean sea level in the Baltic Sea are the land-uplift, the eustatic sea level rise, and the water balance of ...

Satellite measurements of cyanobacterial bloom frequency in the Baltic Sea: interannual and spatial variability

Owing to the potentially harmful character of nitrogen-fixing filamentous cyanobacterial blooms in the Baltic Sea, a capacity to predict their occurrence is of interest. We quantified the surface accumulations of cyanobacteria, mainly Nodularia spumigena, using ocean colour satellite data. The spatial and temporal frequency of the accumulations was mapped with an automated detection algorithm, ...

Near-coastal satellite altimetry: Sea surface height variability in the North Sea – Baltic Sea area

The radiometer wet tropospheric correction is a limiting factor of the application of near-coastal altimetry observations in the North Sea – Baltic Sea area. Using an ECMWF model based correction instead, we increase the return rate from 70% to 95%, with observations as close as 10 km from the coast. The altimetry and 39 coastal tide gauges are referenced to the same state of the art regional g...
