Oxygen-rich water flows into the Baltic Sea – Swedish Radio

Large amounts of oxygen-rich seawater flowing right now into the Baltic Sea. It is autumn calm weather with very low water levels which provided good conditions for new water can get in.

That it now flows into large amounts of salt water into in the southern Baltic can benefit the oxygen-poor and dead bottoms to the Gotland Deep.

But then requires that the heavy salt water do not mix with the southern Baltic brackish surface water without running into the Baltic Sea along the bottom and retains its high oxygen content and cooling .

When the oxygen-rich water then reaches the Gotland Deep penetrating it eliminates the anoxic bottom waters and then increases the oxygen content at the bottom, which favors the benthic oragnismerana.

But unfortunately decreases the oxygen content directly. There according to Jorgen Oberg, an oceanographer at SMHI.

– You can compare with hot water in the bathtub. As soon as you turned off the water begins to cool, he said.
