FM1.3 Intermittently closed and open lakes and lagoons

FM1. Semi-confined transitional waters biome

FM1

Profile summary

Full profile at https://global-ecosystems.org/explore/groups/FM1.3

Brief description

Opportunistic, short-lived organisms live in these ecosystems, where conditions change rapidly as lagoon entrances to the open ocean open or close. Periodic opening and closure influences dynamic gradients in salinity, nutrients, temperature, and water level. Algae, invertebrates like shrimps, and small fish rely on nutrients from land and, when open, the sea. Timing of opening or closing depends on transport of sand and mud by currents or freshwater inflow, or on anthropogenic processes.

Key features

Shallow water systems, highly variability depending on opening or closing of lagoonal entrance. Detritus-based foodwebs with plankton, invertebrates and small fish..

Overview of distribution

Wave-dominated coastlines globally.

Map description

Marine ecoregions (Spalding et al. 2008) containing major or minor occurrences of each ecosystem functional group were identified by consulting global and regional reviews, maps of relevant ecosystems, imagery available in Google Earth and expertise of authors. Occurrences were converted to 30 arc second spatial resolution and clipped to a 20 km buffer along the coastline to exlcude inland and offshore areas of the ecoregions..
