The features of the ocean floor help to determine how water masses and ocean currents move and how they affect our climate. Biodiversity is also influenced by seafloor landforms. Accordingly, the most precise information possible on seafloor topography is indispensable for oceanographic and climate research. With the second version of the International Bathymetric Chart of the Southern Ocean (IBCSO v2), an international group of researchers led by the Alfred Wegener Institute recently presented the best and most detailed seafloor map of the Southern Ocean to date. The map and the complex methods used to create it have been published in the Nature journal Scientific Data.

Lets begin this piece by asking a question; how often do you consider the tides before going for a surf? Playa Guiones, where the Surf Simply resort is based is lucky to work all the way through from high to low. Where the tide is at any given time though may influence certain decisions before we paddle out; like for example where to surf, or which surfboard to ride. Typically at high tide there would be a slow, fatter wave breaking, and a fast more hollow wave breaking at low tide, with those characteristics transitioning through mid tide. This becomes even more critical when we travel up or down the coast
