Ghost shrimp and current Kona Hawaii scuba diving conditions...


Finally, I've got Adobe CS5 on my computer at the shop, and after an update download my camera I bought last year has RAW support... this means, maybe I'll start taking my camera back in the water. I realized the other day that after a year without the camera in the water, I forgot how it works. I didn't even have the zoom/focus ring in the housing so I was pretty much stuck with wide angle, couldn't remember how to change the camera into macro, all sorts of photo mishaps ensued. I did manage to get this ghost shrimp photo though. It was down at 92 feet and this was taken without any type of flash and no zoom control. If you'd see the original photo, it'd be very blue and lacking in detail or color, the nice thing with RAW and underwater photography is that you can set the white balance after the fact and there's a real decent chance in getting the orginal colors back.

Ghost shrimp are also known as Fountain Shrimp in many parts of the world, named after the foutainous spray of their antennae I guess. They're a pretty decent sized reef shrimp, not eatin' size, but big compared to what we usually see.

We've had a pretty good south swell lately, with a fair amount of west in it on occasion. South we can deal with, west can be a problem if it's big enough. From the dive shop I can see things are kind of washed out near Honokohau Harbor (yesterday they were just fine). Tomorrow we have 3 intro divers and a couple of certified divers on the boat, hopefully it'll settle down by then. One of the very nice things about Kona diving is that because of the lack of soil at water's edge, it can be stirred up one day and cleared up the next if the surf settles down. Sand, the limited amount that there is on the reefs here, settles out very fast and we can have 100+ foot viz the day after having poor viz.

Yesterday's diving gave me the first 79 degree reading for an entire dive that I've had this year. Things are finally starting to warm up. It never got "cold" here (by our standards) this winter, but it has yet to really start getting warmer either. Last year it maxed out at about 79 degrees, I'm hoping we see 80/82 later this summer and into the fall. The warmer water temperatures often will hold out through November and early December.
