June 16, 2024 - North Atlantic Ocean - Since May 2024, satellite images have hinted at a phytoplankton bloom developing off the coast of southeast Greenland. But a near-constant stream of clouds prevented optical sensors from getting a clear look. That changed in mid-June, when a short-lived gap in the clouds over the North Atlantic Ocean exposed the bloom's colorful swirls. The bloom is visible in this image, acquired on June 16, 2024, with the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA's Aqua satellite. The image shows an approximately 800-kilometer-wide patch of the North Atlantic Ocean centered east of Greenland and south of Iceland. The bloom stretches many more hundreds of kilometers beyond the edges of this image. Peek-a-Bloom in the North Atlantic, North Atlantic Ocean - 16 Jun 2024

Local Greeks and foreign tourists are protesting against the extensive occupation of the coast of umbrellas and sunbeds in the Greek islands and mainland, a growing nationwide movement against the expansion of expensive rented shadow. Beachbars are occupying larger areas than their permission which do not allow people to have free access to the beach. Similar incidents occurred in Agia Anna and Plaka beach.
