Phytoplankton

A phytoplankton bloom extends eastward, offshore of New Zealand‘s South Island near the Banks Peninsula. The bloom follows the Chatham Rise, an underwater plateau that reaches from the South Island to the East, past the Chatham Islands. The rise separates two areas of deeper water to the north and south.

When ocean currents and tides flow over the underwater plateau, cold waters from the Antarctic mix with warmer waters from the subtropics. This encourages large phytoplankton blooms along the rise, particularly during spring and summertime in the southern hemisphere.
