In the fall of 2020, a long-lasting and massive harmful algal bloom (HAB) with extensive fields of yellow sea foam was observed in relatively cold waters (7-13 °C) off the coasts of the Kamchatka Peninsula, Russia. According to the estimates based on bio-optical parameters in satellite imagery, the Kamchatka bloom 2020 lasted for two months and covered a vast area of more than 300 × 100 km. An abundance of dead fish and invertebrates, including sea urchins, sea anemones, chitons, cephalopods, bivalves were found on shore during the bloom.

Article Synopsis
  • Climate change has altered the thermal structure of lakes, impacting both surface and deep water temperatures, though surface changes are more documented than deepwater trends.
  • This study presents a comprehensive dataset of vertical temperature profiles from 153 lakes, starting from as early as 1894, allowing for a deeper analysis of long-term trends.
  • The researchers also collected various geographic and water quality data to understand how different factors influence the thermal structures of these lakes amid ongoing environmental changes.

Fatty acid composition and content of 2 forms of sockeye salmon Oncorhynchus nerka from lakes in Kamchatka Peninsula (Russia) were compared. One form of sockeye salmon was anadromous ("marine"), that is, adult fish migrated in ocean to feed and grow and than return in the lake to breed. Fish of another form, kokanee, never migrate in the ocean.
