By far the two most memorable trips I made in 2017 were the two trips through the Ross Sea. The southernmost sea in the world, bordered by the Ross Ice shelf to the south and with a range of rarely seen species like the Ross Seal and a special ecotype (or species) of the Orca, type C and also known as the Ross Sea Orca. It is also the place where several historical expeditions left for the South Pole and the first wintering on the continent also took place there.
Later in the year, I wrote a series of blog posts with the reason why the Ross Sea is special and needs conservation. You can read more about that in this post.
