Scientists say sea-level changes formed Australia’s K’Gari Sand Island, Great Barrier Reef

Researchers from Utah State University and the University of Queensland examine sands from eastern Australia's K'Gari (Fraser Island). Their work sheds new light on the formation of the massive sand island, as well as the Great Barrier Reef.

Future Sea-Level Rise May Be Much Higher Than Thought – Ice Loss in Greenland “Vastly Underestimated”

It found ice loss from northeast Greenland could be six times greater by the end of the century than previously thought.Ice is continuously streaming off Greenland’s melting glaciers at an accelerating rate, dramatically increasing global sea levels. New results published in the journal Nature on November 9 indicate that existing models have underestimated…

Sea-level rise ‘may cross two meters by 2100’

A report from the Asian Development Bank recommends raising imaginary waterline demarcation for projects in the Asia Pacific region by two metres instead of one metre to improve resilience against sea-level rise.

Observations confirm model predictions of sea-level change from Greenland melt

As ice sheets and glaciers on Greenland melt and the water is redistributed around the global oceans, sea level does not rise uniformly. New research using high-latitude measurements by satellites confirms computational models that forecast lower sea level around Greenland but higher levels farther away. Credit: Matthew Hoffman Rising sea levels from melting glaciers and ice sheets pose an increasing threat to coastal…

Impact of sea-level fluctuations on redox-sensitive trace-element enrichment patterns in marine sediments

(a) Sea-level regression resulted in highly restricted hydrographic circulation, increased salinity, depleted seawater RSTE, low sediment Mo/TOC and U/TOC, stably stratified water column and euxinic bottom water, and predominant siliceous mudrock deposition. (b) Sea-level transgression resulted in improved deep-water renewal, normal marine salinity, resupply of seawater RSTE, elevated sediment Mo/TOC and U/TOC, destratification of the water column and…

Stanford Scientists Discover Crucial Missing Component of Sea-Level Rise

Researchers have identified an additional process that could have a significant effect on an ice sheet’s future: thawing of the bed, where the ice sheet touches land.Scientists seeking to understand how melting ice in Antarctica will impact the planet’s oceans often use computational modeling. Their recent efforts have focused on ice-sheet geometry, fracture, and surface melting – processes that could potentially trigger or accelerate ice-sheet mass loss. Now, an additional process that could have a similarly significant…

Warm Water Headed Towards East Antarctic Ice Sheet Might Accelerate Global Sea-Level Rise

The warming up of the planet and its adverse effects on the life on Earth is the bleak reality today. A recent study has now added to the worries by revealing that warmer water in the ocean is moving towards the East Antarctic ice sheets and is likely to accelerate the rise in global sea level. This, according to experts, will damage the marine life and threaten human coastal settlements. Researchers were familiar with the melting of the West Antarctic ice sheet and its contribution to the rising sea-level. However,…
