Spring Bloom in New Zealand Waters
Wed, 04 Nov 2009 23:00:00 -0600
Off the east coast of New Zealand, cold rivers of water that have branched off from the Antarctic Circumpolar Current flow north past the South Island and converge with warmer waters flowing south past the North Island. The surface waters of this meeting place are New Zealand's most biologically productive. This image of the area on October 25, 2009, from the MODIS sensor on NASA's Aqua satellite shows the basis for that productivity: large blooms of plantlike organisms called phytoplankton. Phytoplankton use chlorophyll and other pigments to absorb sunlight for photosynthesis, and when they grow in large numbers, they change the way the ocean surface reflects sunlight. Caught up in eddies and currents, the blooms create intricate patterns of blues and greens that spread across thousands of square kilometers of the sea surface. Especially bright blue areas may indicate the presence of phytoplankton called coccolithophores, which are coated with calcium-carbonate (chalk) scales that are very reflective. The duller greenish-brown areas of the bloom may be diatoms, which have a silica-based covering. In addition to their importance as the foundation of the ocean food web, phytoplankton play a key role in the climate because, like plants on land, they absorb carbon dioxide from the atmosphere. When they die, they sink to the ocean floor where the carbon they took from the atmosphere is stored for thousands of years. Photo Credit: NASA/MODIS Rapid Response/Jeff Schmaltz.

Possibly related or possibly not, NZ has had its coolest October since 1945. Persistent SW flow over New Zealand (and consequently cool temperatures) is typical during El Nino years.

Hello Everyone
This is interesting. Such minute organisms can help the balance of our atmosphere.

Spring Bloom in New Zealand WatersBlair,
I did not mean that this has had a direct effect on the current situation. Only that such tiny things can have an overall affect. I just found it interesting that is all.

I meant here that it's possible the ocean circulation which was favourable for the bloom was also favourable for low temperatures and/or may have been influenced by the southwesterly wind anomalies.
