Climate Change Leading to Darkening of Norway’s Fjords

60.3N 4.2E

February 8th, 2013 Category: Climate Change

Norway – January 22nd, 2013

Numerous fjords can be seen along the western coast of Norway in this image. New research has suggested that the waters of Norway’s fjords and coasts are becoming darker as a result of climate change. The darkening is primarily being caused by the increasing levels of organic compounds in the waters, brought to the coasts via regional rivers and lake drainage.

This darker water has been resulting in fewer marine areas with fish, and more with jellyfish. The jellyfish benefit from the darker waters, while the fish have a harder time competing with them because of the increased darkness.

According to University of Bergen marine biologist, Dag L. Aksnes, the process has probably been occurring over many decades. And there is clear evidence that recent changes in weather patterns and in the climate are accelerating it (click here to read more).

Phytoplankton Bloom North of Norway-Russia Border – August 11th, 2012

Russia – August 10th, 2012

Visible off the coast by the Norway-Russia border are the paisley patterns of an intense phytoplankton bloom in the Barents Sea (click here for previous images). The bloom appears most intense to the north, where it has an opaque, milky teal color, while the spirals visible closer to the coast tend to be more turquoise and less intense. These differences may be due to factors such as different species of phytoplankton, the presence of the tiny organisms at different depths in the water, ocean currents, increased or decreased growth rates, etc.

Varanger Fjord in Norway Near Russian Border

Russia and Norway - December 11th, 2011

This orthorectified image shows the Varanger Fjord (Varangerfjorden in Norwegian), left, a vast bay of the Barents Sea, near the border with Russia. It is approximately 100 kilometres (60 mi) long. In a strict sense, it is a false fjord, as it does not have the hallmarks of a fjord carved by glaciers.

The Varangerfjord in the county of Finnmark, is the easternmost fjord in Norway. Its mouth, between the city of Vardø in the north and Grense Jacobselv – near Kirkenes – in the south, is about 70 kilometres (40 mi) wide. The fjord stretches westwards inland to Varangerbotn in the municipality of Nesseby.

Multiple Colors of Phytoplankton Bloom Between Norway and Svalbard Archipelago

Phytoplankton in Barents Sea - August 17th, 2011

Brilliant shades of blue and green created by a massive phytoplankton bloom color the waters of the Barents Sea between Norway (lower right) and the Svalbard Archipelago (upper left). Blooms in this area are common in August, although they are often difficult to observe vi satellite because, according to NASA, the Barents Sea is cloud-covered roughly 80 percent of the time in summer.

The milky blue color of this bloom suggests that it is mostly composed of coccolithophores, microscopic plankton plated with white calcium carbonate. The differences in color may be due to differences in depth and concentration, or the presence of sediments or other species of phytoplankton, particularly diatoms.

Phytoplankton in Fjords of Northeastern Norway

Phytoplankton in Barents Sea - August 15th, 2011

This image offers another view of the intense green and blue phytoplankton bloom near Norway that Eosnap has been observing over the last view days. Here, the bloom can be seen hugging the country’s coastline and within large fjords.

Fjords such as Laksefjord (east) and Porsangerfjord (west), separated by the Sværholt Peninsula, have a bluish-green hue. Also visible further east, at the right edge, is the Varangerfjord, the easternmost fjord in Norway, appearing slightly more blue in color. All three fjords are located in the county of Finnmark.
