When light shines through water, colors with longer wavelengths are absorbed by the water, with the longest wavelengths absorbed first. Blue and violet have the shortest wavelengths of visible light, so they are able to penetrate the deepest.
If you enter the amounts of different types of plastic that you clean up into the Wildlife Impact Calculator, it will tell you how many animal lives would have been at risk, had those items made their way into the ocean and been ingested.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
In Grazalema, Spain's wettest town, a year's-worth of rain fell in a fortnight and overloaded the karst aquifer beneath it. Water rushed into homes through floors, walls and even electricity sockets. Authorities ordered everyone to evacuate. I felt a lot of fear, said Sanchez Barea, a guesthouse owner whose home is one of hundreds still in an exclusion zone.
I've wanted to be an ocean swimmer ever since I moved to Sydney. The idea of getting out past the waves and braving the elements excited me. I would tell anyone who would listen: Once I live closer to the beach, I'm going to be out there. Just you wait. I've lived walking distance to the beach for more than a year now. During this time, I've read a lot about ocean swimming: how swimmers overcame challenges or life-altering moments.
The three-part docudrama Dirty Business, which started on Channel 4 on Monday and concluded midweek, has made the notion of going into the sea in the UK terrifying and unlike Jaws, this story is real. It is an example of what good drama can do that even the best reporting can't quite achieve.
On September 14, Alejandro Carranza, a 42-year-old fisherman, set out to sea from a remote town in La Guajira, Colombia's northernmost province, bordering Venezuela. It was an ordinary fishing trip, in search of tuna and marlin, said Leonardo Vega, a childhood friend and the president of the fishing association Carranza belonged to. But this time, Carranza never returned.
In this photo, I'm preparing drifting buoys for deployment. This was my main responsibility aboard the RV Falkor (too), during a 27-day research expedition in October 2025 exploring the Malvinas Current, an ocean current that runs alongside Argentina. The expedition included biologists, geologists and physical oceanographers such as myself; I'm a PhD candidate at the Sea and Atmosphere Research Center (CIMA) in Buenos Aires, Argentina.
In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.
Northern Monterey Bay and Southern Monterey Bay and Big Sur Coast as well as San Francisco County are under a beach hazards statement which was released by the National Weather Service on Thursday at 12:13 p.m. The statement is in effect until Monday Feb. 2, at 9 a.m. An increased risk of sneaker waves and strong rip currents with breaking waves of 14 to 19 feet, can be expected according to the NWS San Francisco CA.
