Arctic marine ecosystems are principally impacted through alterations linked to worldwide warming. the ocean ice in Greenland Sea performs a massive position in neighborhood and international weather method. The e-book examine the relationships among phytoplankton biomass, measured utilizing remotely sensed chlorophyll-a (CHL), aerosol optical intensity (AOD) and sea-ice conceal (ICE) within the Greenland Sea (20°W-10°E, 65-85°N) over the interval 2003-2012. First hand satellite tv for pc info was once used to do correlation research. more suitable data tools, resembling lag regression approach and cointegration research procedure are used for correlation and regression research among 2 variables (up to three variables). ARMA version was once used to prediction time sequence sooner or later three years. The publication not just supplies define of environment in Greenland Sea, how the ice effect to the neighborhood ecosystems, but additionally offers invaluable statistical tools on research correlations and predicting the long run ecosystems.

Year 2004 had more cloud cover than other years. Year 2009 had the least cloud cover in April. Years 2008 and 2011 had least cloud cover from May to July. April is the month with the most fluctuations, while August and September had the least fluctuations. 7a, b. Hollow dots represent AOD and solid dots represent ICE. Although there was a time lag between AOD and ICE, they had quite strong positive correlations. The peaks of ICE were generally 1 month ahead of AOD. The ice cover in north was much higher than south (right axis).

Chapter 3 Aerosol Optical Depth, Ice Cover, and Cloud Cover Abstract This chapter investigated the relationships between aerosol optical depth, sea-ice cover (ICE), and cloud cover (CLD) in the Greenland Sea in 20°W–10°E, 65°N–85°N during the period 2003–2012.

We still focus on the region 75°N–80°N. 3987. The t test and F test values were all refusing the original hypothesis. 05. 4) is significant. Both ICE and CLD all had influence on AOD. There was a positive relationship between AOD and ICE and less significant correlations between CLD and AOD. However, there were other factors which could be the external driving forces to AOD, hence to the radiative balances. The Arctic anthropogenic aerosol concentration and composition, the commercial shipping through Arctic when sea ice is reduced, and the black carbon aerosol on the snow and ice–albedo are the other three driving forces for AOD.
