If you’ve ever cursed the weatherman when that promised sunshine turned to rain and you didn’t have an umbrella to hand, then the efforts of the boats as they head south from Hong Kong to Auckland on Leg 6 of the Race should be of interest.
As the six boats approached 3°N of the Equator on Leg 6, they all launched drifter buoys into the Ocean to capture a range of data that will help scientists understand how our Oceans function.
We currently have very little scientific information from some of the Oceans the boats pass through, particularly in equatorial regions.
The information is being used by the U.S-based National Oceanic and Atmospheric Administration (NOAA) so scientists have a better understanding of those weather patterns and also the impacts of climate change.
Following Turn the Tide on Plastic’s deployment of the buoy, skipper Dee Caffari said: “Deploying these drifter buoys forms an important part of the Scientific Programme.
“The probe activates once it hits the water transmitting data on swell, wind strength, currents and sea temperature and contributes to our better understanding of how our blue planet impacts upon weather patterns.”
Oceans are the big "weather machines" of the planet with water temperature influencing whether or not a hurricane will form and how strong and persistent it will be.
The deployment forms part of the Volvo Ocean Race Science Programme, which is being financed by Volvo Cars via a contribution from sales of their V90 Cross Country Volvo Ocean Race vehicle.
Anne-Cecile Turner, Sustainability Programme Leader for the Volvo Ocean Race, said: “If you’ve ever checked the weather forecast then you’re one of millions of people who benefits from drifter buoys and the information they gather.
“Our boats are passing through parts of our Oceans about which we have very little data so through our Science Programme, the Volvo Ocean Race is contributing to an expansion of that data knowledge.
“Globally, our seas are being affected by a range of impacts from ocean acidification, temperature rise and plastic pollution. Through the Race we are raising awareness about the issues and exploring the solutions to these problems with a focus on plastic pollution.”
Drifting buoys are the primary source of information on surface temperature and provide the best coverage, compared to other systems, to help understand more about the oceans.
The data is transmitted in near-real time, via iridium satellite, to improve marine forecasts and is especially valuable in predicting rapidly intensifying storms that could otherwise catch seafarers off-guard.
The raw data, collected by the Volvo Ocean Race drifter buoys, is made available, open source, online through the operations centre of the Global Drifter Programme, housed at NOAA’s Atlantic Oceanographic and Meteorological Laboratory in Miami.
During four of the Volvo Ocean Race legs, a total of 28 drifter buoys from the National Oceanic and Atmospheric Administration drifter program are being deployed by each of the vessels, at crucial oceanic regions to measure sea surface temperature and ocean current velocities.
Rick Lumpkin, director of the Global Drifter Program at NOAA, said: “The Volvo Ocean Race is providing NOAA with invaluable data from some of the world’s most isolated places which is helping improve our oceanographic knowledge.
“This will be used by a range of experts around the world to better understand the oceans and any changes to weather patterns.”
