Do You Download Your Dives?   June 21, 2022

Modern diving computers allow you to download information from a dive to your laptop or desktop computer, giving a time/depth graph and other information. Undercurrent is working on a story, and we wonder if you find that feature useful? If so, in what way do you use the information you download? And if you have decided not to download data, let us know why. Email, not forgetting to tell us your town and state.

The Noise of Your Boat Disturbs the Fish.   June 21, 2022

Coral reef fish breed more successfully if motorboat noise is reduced, according to a study published in Nature Communications. Near Lizard Island Research Station on Australia's Great Barrier Reef, researchers from the universities of Exeter and Bristol monitored three reefs with normal boat traffic and three where the traffic was calmed (e.g., slowed down and controlled). During a summer breeding season, the researchers swam every other day to monitor 86 spiny chromis broods. Of 46 nests on reefs where traffic had been calmed, 30 still contained offspring at the end of the breeding season. Only 16 out of 40 still contained offspring on the reefs with no traffic control. However, the researchers stress that limiting boat traffic alone is insufficient to protect coral reefs completely.

Florida Dive Center Owners Finally Convicted.  June 21, 2022

The British owners of the now-defunct Key Largo Scuba Shack, Alison Gracey and Christopher Jones, who evaded arrest after a diver died when their boat, Get Wet, sank at Molasses Reef (Undercurrent January 2012), were extradited to the U.S. from Spain, where they were hiding, In April. They each face up to eight years in jail for involuntary manslaughter. A criminal investigation revealed that Jones and Gracey knew before the tragedy that their vessel needed repairs, but they continued operating Get Wet. The couple were first located by authorities in St. Maarten, but escaped back to Europe, where they hid in various countries until Spanish police caught them after an Interpol 'Most Wanted' notice.

BIG. Big Animals, Big Book.  June 21, 2022

Adventure and wildlife photographers Amos Nachoum and Marko Dimitrijevic have produced a book of dramatic photographs of the amazing land and marine animals they have photographed over the years with Big Animal Expeditions. It’s simply called BIG and takes the reader on a moving journey across the globe with the world's largest animals. The high-quality printed book, which lists for $85, is available here for Amazon's best price.

A diver with safety sausage and flashlight beam as surface markers

Carry a Surface Marker of Some Sort.  June 21, 2022

It seems that more divers get separated and lost from their boat when they are on the surface than when they are underwater. A long safety sausage that can be inflated and sent to the surface on a line even while you are making your safety stop will allow your boat driver to anticipate where you will surface. Should you become stranded in the dark, a fully charged diver’s flashlight beam will tell people where you are. Both are essential items for your safety. Always carry both no matter how benign you think the conditions may be.

No More Pre-flight COVID testing; however, . . .  June 21, 2022

The CDC will no longer require pre-departure testing for travelers returning to the U.S.; however, don't let your guard down. COVID is still out there -- 144,000 Americans each day test positive, says the CDC -- so carry test kits, and if you have symptoms, test yourself. If you pick it up in another country, you'll miss your flight home and be responsible for the costs of a place to stay while recuperating. However, many countries require proof of vaccination or COVID tests for entry, so do your research.
