The temperature of the ocean right at the surface is usually a few tenths of a degree Celsius (0.2 to 0.5 °C) cooler than the bulk temperature just a millimeter below the surface. Even though the difference is small, on a global scale the effect is important for estimating the uptake of CO2 by the ocean. This so-called “cool skin effect” is due to the typical conditions of cooling at the surface that results in a net flow of heat from the ocean to the atmosphere. Dr. Andy Jessup will explain and analyze what the crew from sailing vessel One Ocean has collected to date.
The Around the Americas Expedition is a 14-month voyage, that just launched in May. They will circumnavigate North and South America aboard the 48-foot sailboat, One Ocean. The mission focuses on scientific research, education, and community outreach to raise awareness about ocean health. Building on Captain Mark Schrader’s original 2009–2010 journey, the expedition will compare oceanic changes over the past 15 years.
