Algaline transect measurement API
This dataset provides access to water quality measurements collected by the Algaline flow-through monitoring system, delivered via a WFS service endpoint (layer: algaline:transect_measurements). Algaline consists of automatic sensors installed on commercial ships operating on the Baltic Sea, which continuously record parameters such as chlorophyll and salinity along their transect routes. The dataset is published by the Finnish Environment Institute (Suomen ympäristökeskus, SYKE) and offers a national-scale, ship-based perspective on marine water quality conditions across the Baltic, complementing fixed monitoring stations with continuous underway measurements gathered during regular maritime traffic.**Service endpoint**: https://geoserver2.ymparisto.fi/geoserver/algaline **Service layer**: algaline:transect_measurements *** **[FI]** Palvelu sisältää Algaline-läpivirtajärjestelmän vedenlaatumittaukset. Algaline-järjestelmä koostuu Itämerellä kulkeviin merialuksiin asennetuista automaattisista...
