Our waters are the clearest offshore and in the winter when the sun is low, temperatures decrease and plankton growth is the slowest. However there is always a mixture of creatures drifting in the water; sometimes even fish eggs and larva. |

Hauling a plankton net in the clearest waters in winter (Offshore waters with low Forel-Ule numbers like I-III ) will capture Phytoplankton and Zooplankton in great numbers. Offshore waters with low Forel-Ule numbers like I-III will look clear and blue, but still harbor diatoms, copepods and even salps. |
