Thanks to those that have served in the Armed Forces. You and your families’ sacrifices to America are appreciated. I hope you all have a wonderful day tomorrow.
As for me, I’m going to try and get out tomorrow and do a little local geology. It just rained pretty heavy here at the end of last week, so now that the stream levels have fallen back to normal flow there is a place north of Raleigh that I’d like to go to and take some photographs of some sand and gravel deposits.
UPDATE: I did get up to Lassiter Mill and found some good stuff; however, I’ve got some weather coming and may have to suspend computer activities until the lightning storm passes.
The National Oceanographic and Atmospheric Administration [NOAA] released a revised 2010 Hurricane Prediction today for the Atlantic Basin. This prediction calls for
14-23 named Tropical Cyclones; 8-14 Hurricanes; and 3-7 Major Hurricanes [NOAA, 2010].

I’m often surprised at how many fellow geologists have not heard of this association. AEG [for short] promotes the science and welfare of our profession through a diverse community of professionals, educators, and students. There are chapters for each state—or in the case of the Carolinas Chapter two states—which can be accessed through the AEG website. I can’t really speak for other chapters but the Carolina Chapter has 4 quarterly dinners with presentations. This year we are having a Summer Field Trip in the Asheville, NC area. Cool stuff! We are holding our Fall Meeting in conjunction with the 53rd Annual National Meeting of the AEG in Charleston, South Carolina.

My friend was showing me some photographs the other night as part of a discussion on digital cameras. After sending me this photograph of a school of Jellyfish at the Monterey Bay Aquarium, we started talking geology.

Jellyfish are an interesting organism to say the least. Those shown in the photograph are the adult phase of the marine animal in the phylum Cnidaria called a medusa. Jellies reproduce asexually which in simple terms means that there males and females that both self-fertilize. I’m not going into nut and bolts of that whole part here. However, when the medusa phase reproduces it releases thousands of eggs into the open waters of the ocean. The eggs that fall to the ocean bottom may eventually become larvae. If the larvae reach a solid, hard substrate, their chances of continued life increase during the polyp phase of the cnidarian.
If the polyps grow and proliferate, they extract carbon, oxygen, and calcium from the ocean water. They reconstitute these elements into calcium carbonate if the ocean water temperatures are warm enough, and begin to build an exoskeleton. The exoskeleton becomes a sort of high rise apartment complex for . . . → Read More: Jellyfish
