The Baltic Sea anomaly is a feature visible on an indistinct sonar image taken by Peter Lindberg, Dennis Åberg and their Swedish OceanX diving team while treasure hunting on the floor of the northern Baltic Sea at the center of the Gulf of Bothnia in June 2011.
The time series of area averaged anomalies correspond to the area average of the maps in the Baltic Sea weighted by the cosine of the latitude (to consider the changing area in each grid with latitude) and by the proportion of ocean in each grid (to consider the coastal areas).
Baltic Sea sea level 99th percentile. Left map: mean of annual values over the period 1993-2020; Right map: Anomaly of 2021 with respect to the previous mean. More information Data Access
20 maj 2013 · For assessing local land movements one can also use GPS measurements. Therefore, we have downloaded the available estimates on the land vertical movement in the Baltic Sea from the GPS database provided by SONEL (Système d’Observation du Niveau des Eaux Littorales, www.sonel.org).
14 lis 2024 · Update from 14th Nov. 2024 Previously anomales were calculated with respect to a 1985-2003 climatology based on data from the Pathfinder Project. Now, we apply 1991-2020 climatologies based on data from the Copernicus Marine Service. See data/methods for details.
22 wrz 2022 · Time series of the annual Secchi depth (Z Sd) anomaly for the whole Baltic Sea estimated by in situ (black open circles) and mean-adjusted satellite (red line) measurements.
7 paź 2022 · Did you know there is a map layer on sea level anomalies in the European Atlas of the Seas? It reveals the regional extent of anomalous (i.e. deviating from what is normal or expected) water levels in the coastal seas for a certain time period.
