Integrated ocean modeling systems is helpful for specific regions: for example, the ESPreSSO model is used to study the Mid-Atlantic Bight region. Integrated ocean modeling systems often use data from buoys and weather stations for atmospheric forcing and boundary conditions. Two examples of integrated ocean modeling systems are:
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [1] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.

The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.
Here, the water is chilled by Arctic temperatures. It also gets saltier because when sea ice forms, the salt does not freeze and is left behind in the surrounding water. The cold water is now more dense, due to the added salts, and sinks toward the ocean bottom. Surface water moves in to replace the sinking water, thus creating a current.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Caribou are large-scale migratory animals and have been known to travel up to 50 miles (80 km) a day. The migratory activities of caribou are usually driven by weather conditions and food availability. [16] Changes in caribou migration can be problematic for Alaska Natives, who depend on caribou for food. [16]
The Porcupine caribou is a herd or ecotype of the mainland barren-ground caribou (Rangifer arcticus arcticus, syn. R. tarandus groenlandicus [1]), the subspecies of the reindeer or caribou found in Alaska, United States, and Yukon and the Northwest Territories, Canada.
