What was discovered in the ocean on February 22 2021?

February 22, 2021: Glass Sponge This glass sponge of the genus Caulophacus was seen while exploring on a ridge extending to the southeast of Castellano Seamount, south of the Midway Islands, as part of the 2016 Hohonu Moana: Exploring Deep Waters off Hawaiʻi expedition.

What’s happening in the ocean right now?

Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans.

What is the most recent discovery in the ocean?

These Recent Ocean Discoveries Will Blow Your Mind

  • Scientists Discovered the Largest Bioluminescent Shark Ever Recorded.
  • A Centuries-old Fossil Was Identified as the Ancestor of Today’s Sea Stars and Brittle Stars.
  • Megalodon babies were Enormous … and Sometimes Ate Their Unborn Siblings (oops?)

What is a current marine science?

The term “current” describes the motion of the ocean. Ocean currents are driven by wind, water density differences, and tides. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).

Are there 4 oceans?

Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.

Will the ocean ever be fully explored?

Despite its size and impact on the lives of every organism on Earth, the ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. The average depth of the entire ocean is 3,720 meters (12,200 feet).

Is marine life in danger?

Today, marine life is facing constant threats and dangers and is slowly dying. Some of the threats include oil spills, global warming, overfishing, plastic pollution, noise pollution, ocean dumping and many others.

How much of the sea has been explored 2021?

Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans. That doesn’t seem like it could be true. The oceans account for 70 percent of Earth’s surface.

What are the 3 major ocean currents?

Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.

How fast do ocean currents move?

Horizontal movements are called currents, which range in magnitude from a few centimetres per second to as much as 4 metres (about 13 feet) per second. A characteristic surface speed is about 5 to 50 cm (about 2 to 20 inches) per second. Currents generally diminish in intensity with increasing depth.
