The beauty of the place is absolutely breathtaking above and below surface. The dive follows alongside the jungle and is shaped like a horseshoe. The diver or snorkeler will experience beautiful light penetration, halocline and a mix of fresh and saltwater fish species because of the location right next to the ocean.

Halocline ocean

The upper halocline of the Arctic Ocean has a distinct chemical signature with high nutrient concentrations as well as low oxygen and pH values. This signature is formed in the Chukchi and East Siberian Seas, by a combination of mineralization of organic matter and release of decay products to the sea ice brine enriched bottom water. A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g.

These waters cross the shelf break at ~ 140° E and feed the low-salinity halocline water (LSHW, salinity S 33) in the upper 50 m of the water column. High silicate concentrations in Laptev Sea bottom waters may lead to speculation about a link to the local silicate maximum found within the salinity range of ~ 33 to 34.5, typical for the Lower Halocline Water (LHW) at the continental slope.
