sediment bank

Old sediment bank

1. Kangerlussuup glacier

Grinds bedrock into a fine sediment, ejecting it into the fjord and piling it in a high bank

 

2. Nereid Under Ice (NUI)

Takes core samples of the sediments piling up at the glacier’s foot

 

3. Sediment banks

May disrupt inflow of warmer ocean currents, possibly slowing glacier melt
