![]() Details on the distribution and trajectory of icebergs within the model may also be of use for understanding potential navigation threats, as shipping increases in northern waters.Īntarctic icebergs distributions 1992-2014 To do that, we use an interactive iceberg module coupled with the Nucleus for European Modelling of the Ocean (NEMO v3.4), which will calve icebergs from Greenland according to rates established by Bamber et al. Our study aims to evaluate the distribution of icebergs originated from Greenland and their contribution to freshwater input in the North Atlantic. Icebergs originated from the Greenland ice sheet, in particular, can affect the subduction process in Labrador Sea by decreasing surface water density. While liquid runoff decreases the ocean salinity near the coast, icebergs are a gradual and remote source of freshwater - a difference that affects sea ice cover, temperature, and salinity distribution in ocean models. However, an important source of freshwater has often been overlooked or misrepresented: icebergs. Numerical studies have examined the AMOC's variability under the influence of freshwater input to subduction and deep convections sites. The Atlantic Meridional Overturning Circulation (AMOC) is well known for carrying heat from low to high latitudes, moderating local temperatures. Exploitation of the iceberg upon arrival could also include its use as an energy sink. Innovative equipment for tugboats and a refrigerated drydock to retard melting could minimize some of the towing problems. They suggest that time spent in selecting favorable icebergs will improve the economics. The authors describe the nature of icebergs, some of the technical problems of towing (such as wind and ocean currents and the ratemore » of melting), and possible environmental impacts when the iceberg arrives at its destination. Several development proposals have been made for Southern California, Australia, and the Middle East. Most of the fresh water ice is in the Antarctic Ice Sheet, which has tabular icebergs of regular shape and comparatively easy access for towing to the Southern Hemisphere. The feasibility of melting icebergs to obtain supplies of liquid fresh water is, while still undemonstrated, worth considering in view of the nearly 30 million cubic kilometers of fresh water ice in the world. John’s.DOE Office of Scientific and Technical Information (OSTI.GOV) Other popular spots along Iceberg Alley include Gros Morne National Park, Cape Spear Lighthouse, and St. ![]() From here, you can take boat tours out onto the water for an up-close look at the icebergs, or go hiking and whale watching along the coastline. The most popular spot is probably Twillingate, which is located about halfway up Iceberg Alley on Newfoundland’s northeast coast. There are a few different places along Iceberg Alley where you can get up close and personal with these giants of the sea. However, even if you miss the early part of iceberg season, there will still be plenty of beautiful icebergs to see later in the season. The best time to see icebergs is typically early in the season, before they start melting and breaking apart. Iceberg season typically runs from April to June, but the exact timing can vary from year to year depending on weather conditions. □ #Iceberg Alley □❄️ □ #newfoundland #canadatravel #canadatok #visitcanada ♬ original sound – Visit
