   On April 3, 2023, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Aqua satellite acquired a true-color image of
   the southern section of the Gulf of Bothnia.

   The cloud-free skies allow an expansive view of the dark waters bounded
   by the snow-covered landscape of Sweden (west) and Finland (east). In
   the south, the Aland Islands sit at the boundary of the Gulf and the
   Baltic Sea. The Aland Islands, which belong to Finland, consist of
   about 35 inhabited islands, more than 6,000 uninhabited islands and
   rocky reefs. The largest island, Fasta Aland, contains about 70 percent
   of the total land mass of the archipelago.

   The northern section of the Gulf of Bothnia, also called the Bothnian
   Bay, sits out of sight and to the north of this image. It is shallow,
   with an average depth of about 42 meters (138 feet). The southern
   section, called the Bothnian Sea, is deeper, dropping to a maximum
   depth of 294 meters (965 feet). At this time of year, the northern
   section of the Gulf remains covered with ice, while the southern
   section (also called the Bothnian Sea) appears almost entirely ice
   free, with the exception of a small amount of fast ice which can be
   seen clinging to the coast of Finland at the northern reach of the
   Bothnian Sea.
