I was able to hook up with Carol and Larry Cohn for a dive Saturday, December 8th on XTA Sea, AKA Carolís RIB. The goal was to get to a site that would be manageable to dive and do a Reef survey of fish and invertebrates. The forecast was a little iffy on the more exposed sites. We decided to drop anchor at Hopkins Deep Reef. We suited up into our gear and I hooked my survey slate to one of my D-rings and off we went. We were surprised to see the conditions were very good. About 30ft-40ft of vis. Depth range was 60-73ft, bottom temps: 55F, Habitat: Reef

Here is a video of Hopkins Deep Reef

Shale Island was also survey and data collect.

The species I Identified while meandering around on the reef were the following.
The codes we used to record the amount of fish and invertebrate are from the Reef.org survey protocols, which are the following:
S-single; F-Few (2-10); M-Many (11-100); A-Abundant>100; P-Present

Hello D,

Nice to see you working on the surveys.

One question: Do you have a plan to enter this data in some kind of database (can we simple) so you can create queries or graph with the data over time? It would be nice to think about the repository for this information so it works well for future.

Cheers
Beto
