Melt ponds result in more life in sea: Study

The ,melt ponds, make the ice darker, so it absorbs, rather than reflects light and thereby it heats. This accelerates the melting process. Satellite photos show that areas with ,melt ponds, are ...

Arctic Sea Ice: Melt ponds
Arctic Sea Ice: Melt ponds

Melt ponds - and to a lesser extent openings within the ice pack - are important because they lower the ice pack's albedo and soak up a lot of sunlight, preconditioning the ice for further melting. This melting momentum , as I call it, can play a decisive role in the latter half of the melting season, trumping weather conditions.

Melt ponds (MPs) are pools of open water that form on sea ice, glacial ice or ice shelves in the short Arctic summer. Areal coverage of MPs has been estimated to reach up to 80% of the Arctic sea ice in summer (Lüthje et al., 2006).

Melt ponds have key impacts on the evolution of Arctic sea ice and summer ice melt. Small changes to the energy budget can have significant consequences, with a net heat-flux perturbation of only a few Watts per square metre sufficient to explain the thinning of sea ice over recent decades.

The contribution of melt ponds to enhanced Arctic sea-ice melt during the Last Interglacial [in review] HadGEM3 is the first coupled climate model to simulate an ice-free Arctic during the Last Interglacial (LIG), 127 000 years ago. This simulation appears to yield accurate Arctic surface temperatures during the summer season.

Abstract. Melt ponds occupy a large part of the Arctic sea ice in summer and strongly affect the radiative budget of the atmosphere–ice–ocean system. In this study, the melt pond reflectance is considered in the framework of radiative trans-fer theory. The melt pond is modeled as a plane-parallel layer

May is the month when melt ponds start to form on the ice, pools of water that lower the albedo and cause the ice to melt faster, leading to open water that absorbs solar radiation and warms up. The open water is already there in the Beaufort Sea. Look at all that open water!

Lifecycle of melt ponds Stage I: Snow melt; lateral melt water transport dominate vertical drainage; drainage in flaws; some underwater ice formation (late May – 20 June) Stage II: Lateral and vertical melt water transport; reduction of hydraulic head (height of pond above sea level); flaws enlarged; “false bottom” (20 June – 20 July)

Melt ponds, on thicker ice tend to be turquoise and those on thin ice dark blue to black", explains Dr. Marcel Nicolaus, sea ice physicist and ,melt, pond expert at the Alfred Wegener Institute.
