| Description |
An East wind of 17 knots created a disturbed sea. The beach from the Barham river mouth to Marengo had a continuous deposit of light detrius left behind at the high wave mark. Objects included clear jellies, light seaweed especially floats, sponges, feathers and blue jellyfish with a sail. No large seaweed or shells were present. The blue jellyfish with sail are identified as "By-the-wind Sailor" [Velella velella]. Their number on the beach would exceed 2 thousand individuals. They were mostly 2 to 3 cms in length. The weather had been ESE to East. The following day I observed only one individual, the others either washed out to sea or covered by sand. |
