Landscape and scale

The Caspian has no natural outlet to the world ocean. Water level changes with river inflow, evaporation and climate variability.

Water, climate and life

Kazakhstan's coast includes ports, oil and gas infrastructure, fisheries and protected areas. Aktau and Kuryk connect rail and road networks with maritime transport.

People and infrastructure

Pollution and level change affect different coastal areas unevenly. Sturgeons and the Caspian seal require transboundary conservation measures.

Data and limits

The Caspian's legal regime is defined by coastal-state agreements and is not identical to that of the open sea. Current water level and ecosystem condition must be accompanied by an observation date.

Chronology

Chronology does not apply. This is an overview of a spatial system; change is tracked through dated maps and observation series.
