00:04Way back in 2013, an oceanic heat wave developed in the Pacific.
00:08Science Alert reports it stretched from Alaska all the way down to Mexico, and it produced toxic algae blooms,
00:13messed with oceanic ecology, and caused birds that rely on fish to starve.
00:18In fact, according to Earth data, the heat wave triggered a temperature jump in the waters off the coast of
00:22Oregon,
00:22causing them to skyrocket some 12.6 degrees Fahrenheit in a single hour.
00:27Now, the U.S. National Oceanic and Atmospheric Administration says these types of events don't just happen on the surface.
00:32They can also occur on the bottom of the ocean as well.
00:36What's more, they can be even more extreme and last even longer than the one experts clocked in 2013.
00:41Previous studies have relied almost solely on buoy data to track these events,
00:45but the researchers say oceanic heat waves occurring deep underwater might not affect surface temperatures at all.
00:50Writing in their new report, quote,
00:51Not only do bottom marine heat waves tend to persist longer than their surface counterparts,
00:56but there are many regions where bottom marine heat wave intensity tends to exceed surface marine heat wave intensity for
01:01the same location,
01:02spiking as much as 9 degrees Fahrenheit on the ocean floor.
01:05With the researchers adding that since we often have no indicators on the surface,
01:08we might only see its deadly effects long after its impact has already begun to show.
