is the GPD density function. The additional parameter of interest that needs to be estimated to compute return periods is λ the Poisson rate of exceedance, indicating the expected annual number of events exceeding the threshold μ. According to the GPD definition, the expected number of events ...
Distribution of Sea Ice Density and Air Porosity along the Coast of the Bohai Sea渤海沿岸海冰密度与空气孔隙率分布特征渤海海冰实密度表观密度空气孔隙率Density is an important physical quantity of sea ice, generally ranging from 0.72g/cm3 to 0.94g/cm3. Sea ice density is affected by many factors...
(due to higher average density of the air above compared to an adjacent region). The converse is also true for lower pressure where the air aloft is warmer than the surroundings (so-called ‘thermal lows’). This relationship is the opposite to that described above for upper airgeopotential ...
A combination of GPR data, as well as ice impurities, porosity, density, and temperature, provides insights into the variability of radar transmission speed and the equivalent dielectric permittivity in river ice. The results show that the radar transmission speed falls between 0.141 m/ns and ...
we found that the acceleration is a widespread signal that extends from the coasts of the Gulf of Mexico up to Cape Hatteras in North Carolina and into the North Atlantic Ocean and Caribbean Seas," he said in a statement, "which is indicative for changes in the ocean's density and circula...

the sea-level does not rise by the same amount all over the globe due to the effects of the earth’s rotation, local coastline variations, changes in major ocean currents, vertical movements of the earth’s crust (up and down), and differences in tidal patterns and sea-water density. ...
WhereVis the gate-normal ice velocity,His the ice-equivalent thickness,wis the pixel width and ρ is ice density (917 kg m−3). We use “flux gate 1” (or FG1) from ref.65for our flux gate, which follows areas of direct bed observations and low bed elevation error, rather tha...
The dependence of the air–sea interactions over the North Atlantic on the ocean dynamics is explored by analyzing multicentury integrations with two different coupled ocean–atmosphere models. One is a coupled general circulation model (CGCM), in which both the atmospheric and the oceanic components...
(where colder waters were located) we found higher Chl-a values, reaching 1.5 mg m-3. Similar Chl-a patterns in anticyclonic eddies in, and to the north of, the Southern Antarctic Circumpolar Current Front were previously observed45. It has also been observed that submesoscale density fronts ...
