Seafloor sediments are useful recorders of worldwide climate change because the numbers and types of organic remains included in the sediment are indicative of past sea-surface temperatures. Using oxygen isotope analysis (18O/16O ratios), scientists can use the ratio found in the shells of microorganisms in sediment and layers of ice and snow ...

into the sea are changing. On the other hand, ice shelves. are floating ice bodies and their collapse does not contribute to sea level rise; however, they are known to buttress . outlet glaciers. which drain the large. ice sheets into the sea. The loss of these ice sheets would have a significant impact on sea level.

Passive microwave data provides measurements of the ice edge, sea ice concentrations, and classification of different types of sea ice types. Passive microwave imagery is available from late 1978 through the present. Earlier but less reliable data from the ESMR are available from late 1972 to 1976. Past and Current Platforms.

Vehicles – Not only do the vehicles tear up the surface of the sea ice, but they also bring foreign objects onto the ice surface. These objects attract solar heat and can melt their way through the ice. Crack Types. Cracks form in areas where sea ice is being affected by environmental, geographical and/or mechanical factors.

Land-based ice that covers the landscape across large areas. Examples include the Greenland ice sheet and the East and West Antarctic ice sheets. Melting of ice sheets would cause sea level to rise. Ice Shelves. A thick platform of ice that is floating on the ocean, but attached to land (grounded).

The aims are achieved by compiling a database of earlier information on ice loads and ice pressures. This is a collection of full scale ice load data measured on board ships of various types sailing in different sea areas. Ice load data sets are used in validation of deterministic ice load models. The ice loading process has a stochastic nature.
