Freshwater Plants

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

These are all true plants. In freshwater, much of the algal growth is in the form of slimes that grow on rocks, plants, and other surfaces, and of course microscopic phytoplankton. While freshwater algae is an important part of the ecosystem, it is not very remarkable to the typical scuba diver.

Fishing vessel Susan Rose was bound from her home port of Port Judith, Rhode Island to Manasquan to begin fluke fishing off New Jersey. Instead, just before 5AM * Friday November 17, 2023, she ran aground approximately 350 yards ** south of the inlet centerline. All four crew were safely gotten off. After de-fueling and de-watering, she was successfully pulled off the beach on the second attempt, at about 2AM Sunday morning, after rolling in the rough surf for almost two days. The vessel rapidly filled with water, capsized and sank, a few hundred yards ** off the beach, in approximately 50 feet of water. Again, everyone was gotten off safely.

* about 90 minutes after low tide
** news reporters said half a mile, but ... well, reporters
