Chlorophyll a, Ice Cover, and North Atlantic Oscillation

Chapter
Part of the SpringerBriefs in Environmental Science book series (BRIEFSENVIRONMENTAL)

Abstract

This chapter investigated the relationships between phytoplankton biomass, measured using chlorophyll a (CHL), sea-ice cover (ICE), and North Atlantic Oscillation (NAO) in the Greenland Sea in 20°W–10°E, 65–85°N during the period 2003–2012. Remote-sensed satellite data were used to do correlation analysis. Enhanced statistics methods (such as unit root checking, lag regression, and co-integration analysis methods) are used for correlation analysis. Results show that the melting ice (MI) played a significant role on promoting the growth of CHL. In general, ICE reached peak (in March) 3 months ahead of CHL (peaked in June), and CHL was higher in south and lower in north. CHL increased around 10 % in spring and early summer during last 10 years in 75°N–80°N. Moreover, CHL was higher in 75°N–80°N region where ice melted more and the water column was more stable. The peak of CHL in 2012 was 1 month later than the other years. The CHL peak in 2011 was highest, and there were two peaks in 2010. The peaks of CHL came later in 2012 and 2008. The early and higher peaks of CHL in year 2010 was due to the more MI happened in that year, Other reasons including the stronger wind speed in spring and special wind direction from southeast changed to southwest, plus lower SST and PAR in summer and negative NAO through the year. The research shows that CHL, ICE, and NAO were correlated with a time lag. CHL and ICE had long-term equilibrium relationship. The NAO and MI had a negative correlation. NAO affected the MI and its peak was 3 months ahead of the MI. The CHL and NAO also had negative correlations. With NAO reached to its peak, CHL almost reached to its valley at the same time.
