Oceans cover 70% of Earth's surface, yet remain largely unexplored, particularly the deep sea.
Zero eliminates diesel engines entirely, replacing them with an all-electric power and propulsion system with a DC grid at its core, and photovoltaic-thermal panels that capture the light and heat of solar energy.
Windrose is a sprawling survival crafting game, featuring base building, multiplayer, and some damn-hard-to-kill boar. It's this part of the game that might end up being a roadblock for those just wanting to sail the seas with a crew of singing pirates.
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.
The Titanic was one of a trio of similar White Star Line ships completed in the early nineteen-tens. In the video above, Bill Hammack, known on YouTube as Engineerguy, tells the story of not just the Titanic, but also the Olympic and the HMHS Britannic. An engineering professor at the University of Illinois, he found in the campus library issues of the journal The Engineer published between 1909 and 1911 that contain detailed photographs of the construction of both the Titanic and Olympic, sister ships that were built side-by-side.
In February 2023, an article in the Mexican press announced the capture of a vessel some 195 nautical miles from the port of Lazaro Cardenas in the state of Michoacan. It had been carrying nearly 700 pounds of cocaine packaged in plastic-wrapped bricks, in addition to 1,650 liters of hydrocarbons in 33 plastic containers. Two Ecuadorian fishermen were among the five detainees, and their immigration records showed unusual activity.
Counting Ships is a photography series by Pierfrancesco Celada that examines proximity, movement, and scale within a maritime landscape. The project captures a busy ferry route connecting an island to one of the most densely populated regions nearby. The crossing takes approximately 25 minutes and passes through one of the world's most active maritime trade corridors, where more than two hundred cargo ships transit daily.
'Orcas are psychos,' quipped a close friend recently. He wasn't joking, nor was he ill-informed. In fact, he is probably the world's leading historian of whales and people. He had just watched a BBC Earth clip, narrated by David Attenborough, in which three killer whales separate a male humpback calf from his mother in the waters of Western Australia. The video's closing footage, with two of the orcas escorting the naive youngster to his imminent death, resembles nothing so much as a kidnapping:
Countless books, movies and television shows chronicle the adventures (or misadventures) of people stranded on remote islands. Consider, for example, Daniel Defoe's Robinson Crusoe, the beloved Tom Hanks movie and the classic 1960s sitcom " Gilligan's Island." Now , a new Sam Raimi horror-thriller about a woman (played by Rachel McAdams) stuck with her overbearing boss (Dylan O'Brien) after a plane crash, is set to join the ranks of these survivalist stories.
In 1916, subway construction near Greenwich and Dey Streets in Lower Manhattan unearthed a surprising relic. Some 20 feet underground, workers turned up charred timber; digging further, the contours of an ancient ship came into view-its prow, keel, and ribs. The wreck was later deemed to be the Tyger, a 17th-century vessel that represents a rare archaeological trace of early Dutch exploration in Manhattan.
For decades, whale watching has been a seasonal ritual along the Sonoma Coast, drawing locals to wind-swept bluffs, binoculars in hand. Now the pastime has earned national notice: Travel + Leisure has declared Sonoma County the best place in the country to see whales. In a story published Feb. 3, the magazine said there is no better place in the United States for whale watching than the stretch of coastline from Bodega Bay to Gualala and no better time than now.
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.
Narratives about deserted islands often depict the ingenuity required to build shelter and acquire food and water, as well as the mental fortitude needed to patiently wait for rescue. Many of these story lines are exaggerated and sensationalized for dramatic effect. Still, the challenge of being pitted against nature, secluded from civilization and forced to live with only the barest essentials taps into themes of resilience and adventure that have always fascinated humans.
For travelers looking to get to know the many-varied charms of the Golden State, discovering it through the best beaches in California is never a bad idea. The state's coastline spans a vast 3,427 miles after all. Among its 420 public beautiful beaches are plentiful opportunities to swim, lay out, look at tide pools, surf to your heart's content, or watch the sunset.
