Sentences with phrase «sea deep water formation»

In addition to the main threshold for a complete breakdown of the circulation, other thresholds may exist that involve more - limited changes, such as a cessation or diminishment of Labrador Sea deep water formation (Wood et al., 1999).

Not exact matches

They play an important role in the formation of new sea ice and deep water.

The thermohaline circulation of the global ocean is controlled in part by freshwater inputs to northern seas that regulate the strength of North Atlantic Deep Water formation by reducing surface seawater density.

By Year 1.1 billion, deep - sea hematite - bearing rock found in the Marble Bar chert formation of northwestern Australia indicates that iron - rich water gushed from volcanically heated seafloor vents were able to mix with cooler oxygen - rich seawater (Ohmoto et al, Nature Geoscience, March 15, 2009; PSU press release, and in EurkaAlert; and Sid Perkins, ScienceNews, April 11, 2009).

Here you can learn about coral formations and the different varieties of tropical fish, as well as explore the coastal waters through deep sea diving or cave diving.

Snorkeling and scuba diving reveal wonderful coral formations teeming with marine life, while sailing, deep - sea fishing and glass - bottom boat rides offer ways to enjoy the clear ocean waters.

As sea levels rose during the last Ice Age, the cave flooded and its roof collapsed into this sinkhole resulting in a marine wonder known for its sparkling blue waters, wealth of coral formations, sharks and fish, and deep caves filled with stalactites.

Possible sites include: Bandit Ledge: The gentle hills and ridges of this site support a surprising amount of beautiful cauliflower corals Garden Eel Cove: The slow drop - off ends in a sandy bottom covered with graceful garden eels Anglers: A beautiful archway housing a big family of lionfish High Rock: A massive ridge capped by a pinnacle rising to within 10 feet (approx. 3 meters) of the water's surface Anchor Drag: A maze of canyons, arches small caverns provide enjoyable exploration of the lobsters, crabs, shrimp and puffer fish who live here North Golden Arches: The main attraction is a rock arch with scattered coral heads throughout the area South Golden Arches: A large rock arch with a sandy area, housing numerous marine animals Harlequin: A great spot for a deep dive to see large schools of fish Kaloko Arches: The main attractions here are the unique rock outcroppings and lava formations Turtle Pinnacle: One of best sites to find green sea turtles Eel Cove: Interesting and rapid drop - off for deep diving Thunder Reef: Good spot for viewing deep - water animals West Kaiwi: This dive site is one of the best for observing fish, with lots of coral and a nearby drop - off Please note: This is not an introductory dive.

I contend that a likely trigger of the D - O events is the same sort of local break of an instability «cap» which initiates an intense episode of Deep Water formation — either in the North Atlantic or in the Antarctic seas (the latter is more likely the case in today's climate).

The retreat of the Arctic sea ice in recent decades is moving the egdge of the sea ice away from the areas of deep water formation and I would have thought that this would contribute to a weakening of amoc south of Greenland.

The blue curve shows an early decrease already in the 19th century, which Thornalley and colleagues attribute to an earlier warming at the end of the so - called «Little Ice Age», when the inflow of meltwater could have slowed the formation of deep water in the Labrador Sea.

The resulting formation of Antarctic sea ice expelled colder, salty waters that filled the abyss and began cooling the deep oceans.

The cooler Arctic then promoted formation of North Atlantic Deep Water (NADW in the upper frame of Figure 13) as salty Atlantic waters transported poleward cooled and brine rejection increased as more Arctic sea ice formed.

Extreme scenarios of climate change predict changes in the site of deep - water formation and a weakening of thermohaline circulation, which could result in changes in the oxygenation and biogeochemical cycles in the bottom layers of the deep Mediterranean Sea [148].

These results also increase our overall understanding of glacial − interglacial cycles by putting further constraints on the timing and strength of other processes involved in these cycles, like changes in sea ice and ice sheet extents or changes in ocean circulation and deep water formation.

The temperature signal in deep ocean δ18O refers to the sea surface where cold dense water formed and sank to the ocean bottom, the principal location of deep water formation being the Southern Ocean.

With the use of a climate model of intermediate complexity, we demonstrate that with mwp - 1A originating from the Antarctic Ice Sheet, consistent with recent sea - level fingerprinting inferences, the strength of North Atlantic Deep Water (NADW) formation increases, thereby warming the North Atlantic region and providing an explanation for the onset of the Bølling - Allerød warm interval.
