Greenland, World Waters and Their Water World Life Affect Each Other

Summary: Greenland, world waters and their water world life affect each other, according to Helen Czerski Oct. 3, 2023, in The Blue Machine: How the Ocean Works.

"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.

“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Greenland sharks (Somniosus microcephalus) abide in coastal ocean waters between Canada and Greenland and along east, south, west Greenland; around Iceland and Svalbard; from northwesternmost Russia, around northern and western Europe, through coastal northwest Portugal. They access cool and warm waters elsewhere by their affinity with 400-meter (1.312.33596-foot) depths down. The Caribbean ocean basin, for example, affords them such depths downward to 4,200 meters (13,779.5276 feet). Its temperatures there around 0 degrees Celsius (32 degrees Fahrenheit) agree with them even as its temperatures at 4 degrees Celsius (39.2 degrees Fahrenheit) in the Belize Barrier Reef agreed with the Greenland shark amassed August 2013 among deep-sea fish communities around the blowout site of the Deepwater Horizon oil rig Tuesday, April 20, 2010. Arctic thaw and global warming perhaps aggregate Greenland sharks away from their native, natural areas; "In the last couple minutes of the last dive of the field season, we found the largest fish we have ever encountered with the ROV, a Greenland Shark," image courtesy of the NOAA Office of Ocean Exploration and Research, Northeast U.S. Canyons Expedition 2013: Not subject to copyright, via NOAA Ocean Explorer Okeano

Greenland, world waters and their water world life affect each other, according to University College London oceanographer and physicist Helen Czerski Oct. 3, 2023, in The Blue Machine: How the Ocean Works.

Dr. Czerski broaches world-largest island, Greenland, as world-largest landmass all within the Arctic region, 80+% within the Arctic Circle, all north coast along the Arctic Ocean. She considers Greenland for the latter Denmark-dependent, home-ruled territory configuring underwater currents, ocean walls and waterfalls that connect latitude-, season-, sunlight-commanded world waters. She describes equatorial near-surface waters as 30 degrees Celsius (86 degrees Fahrenheit) even as she designates Arctic near-surface waters as -1.8 degrees Celsius (28.76 degrees Fahrenheit).

Our Earth epitomizing northern and southern hemisphere-curving expressions away from our Sun explains Gulf of America heated Belize Barrier Reef and Greenland shark-existing, heatless Greenland waters.

The research vessel R/V Apalachee found a Caribbean-frequenting Greenland shark (Somniosus microcephalus [from Latin somnium -osus, “sleep -ose”; Greek μῑκροκέφᾰλος, “small[-]head via Latin mīcrocephalus) August 2013.

That research team gathered deep-sea fish communities to gauge Caribbean oil-spill impacts from the Deepwater Horizon oil-rig blowout in the Macondo Prospect Tuesday, April 20, 2010. The hook that harvested that brown-gray, 3.7-meter- (12.1391-foot-) long juvenile hung 1,749 meters (5,738.189 feet) below surface waters 6,758 kilometers (4,199.227 miles) south of coastal-south Greenland. The afore-indicated research team identified Belize Barrier Reef deep-water temperature and therefore the deep water-itinerating temperature of their hook at 4 degrees Celsius (39.2 degrees Fahrenheit) Greenland, world waters and their water world life.

Greenland water world life, such as Greenland sharks journeying 1 meter (3.28084 feet) every 4 seconds, jubilate world waters of water world life and vice versa.

Warm surface waters in the Gulf of America know 100- to 200-meter (328.08399- to 656.167979-foot) thicknesses even as Gulf oceanography kindles a near-4,000-meter- (13,123.3596-foot-) deep basin.

Greenland sharks live in temperatures around 0 degrees Celsius (32 degrees Fahrenheit) at 400-meter (1,312.33596-foot) below-surface depths in the ocean waters that link Greenland and Iceland. So how might they master moving from their meals where flounder, seal and skate matter in cold, deep, dense, salty waters at the afore-mentioned depths downward? Greenland and Iceland waters niche a shallow water-topped underwater mountain south-southwest of the cold-, deep-, salty-watered Arctic Ocean and north-northeast of the warmer-temperatured North Atlantic Ocean.

Greenland, world waters and water world life occur at the 100- to 300-meter- (328.08399- to 984.251969-foot-) deep waterway occasioning the world-largest waterfall, the Denmark Strait Overflow.

The three-million-cubic-meter overflow every second, like the underwater current from Greenland 1,200 miles (1,931.2128 kilometers) eastward to northern Norway, permits the Greenland shark to peregrinate elsewhere.

Two- to three-kilometer-deep basins of the Arctic and the Atlantic Ocean quarter native Greenland sharks even as their global-warmed surfaces queue non-native bluefin tuna (Thunnus thynnus). The East Greenland Current rounds south Greenland’s Nunap Isua (“Cape Farewell”), runs into the Gulf Stream and realizes that Atlantic-Ocean region’s rewarding char-, flounder-, halibut-fishing industry. Its Arctic silhouette and such resources as radioactive uranium and rare earths suggest Arctic-thawed, global-warmed stresses strained by air, land, water pollution without sagely, strict supervision.

Bluefin tuna and Greenland sharks respectively in Greenland and world waters tell us to treat Arctic thaw, global warming, Greenland mining, water world life Greenland-thoughtfully, Greenland-unthreateningly.

The eastern and the western Atlantic Ocean and the Mediterranean Sea announce themselves as native areas of bluefin tuna (Thunnus thynnus). Arctic thaw and global warming perhaps anticipate a different arrangement for these near-surface animal sentients who approach 500- to 1,000-meter (1,640.42- to 3,280.84-foot) depths in their below-surface dives into colder, darker, denser, saltier waters.
