We've taken a look back at the case studies entries we've produced this year and compiled a list of our most popular studies in 2022.
Our case on Hunga Tonga-Hunga Ha'apai major eruptions the gained the most visits and the the most engagement on social media.
2022 case studies
1: Hunga Tonga-Hunga Ha'apai major eruptions
In January 2022 the underwater volcano Hunga Tonga-Hunga Ha'apai in the Pacific Ocean erupted twice causing major gravity and shockwaves to reverberate around the world.
2: Heatwaves across Western Europe
Extremely high and persistent temperatures across west Europe and UK led to widespread heatwaves and wildfire outbreaks in mid-July 2022.
3: Phytoplankton bloom in the Black Sea
Intense and colourful bloom of various phytoplankton species across the Black Sea in early July 2022.
4: Hydrogen sulphide plumes off the Namibian coast
High biomass phytoplankton blooms lead to deoxygenation and the release of hydrogen sulphide in Namibian coastal waters, with devastating impacts on marine life and regional fishing activities.
5: Widespread dust intrusion across Europe
A continental-wide plume of Saharan dust extended across the Mediterranean Sea up as far as northern Europe in March 2022.
6: What has Meteosat-8 seen in 20 years?
As Meteosat-8 headed into retirement, we took a look back at some memorable moments captured by the first Meteosat Second Generation satellite.
7: Winds drive deep water formation in Gulf of Lion

8: Antarctic sea ice at a long-term minimum
The Antarctic ice is completing the seasonal melting phase, following the Antarctic summer. The extent of the sea ice at the end of February 2022 is the lowest in the last 44 years - the period when satellites have been used to monitor the ice.
9: Marine heatwave intensification threatens coral reef health
The past four decades experienced a dramatic increase in number and intensity of marine heatwave episodes. These episodes of persistent anomalously warm ocean temperatures pose a serious threat to the health of marine ecosystems around the globe.
