REA (Rapid Ecological Assessment) Team A: 2 sites outside,
many Ulua, some small Galapagos sharks. Dominant corals
- Porites lobata and Porites compressa; 5-20%
coral cover. Second richest in terms of number of coral
species. Monk seal sighting. Lobsters. Inside dive - juvenile
Scarids, Porites compressa towers. Turf algae
dominated and cyanobacteria.
(Rapid Ecological Assessment) Team B: 3 dives - all
outside the reef crest. The hard bottom spurs were dominated
by the green alga Microdictyon. Every dive we had
15-30 Ulua companions. The question is: Did they follow
us site to site?
Team : Set
new permanent monitoring transect in pass. Ground truth
Northern backreef. Took spectra of Lyngbya algae
near wreck on Eastern backreef.
Archaeology : Surveyed two wrecks - the SS Quartette
and a freighter sunk in 1952, as well as an unknown wreck
site on the Northern reef (maritime power plant, shafts,
Surveyed East Seal-Kittery and Grass Island's intertidal;
shallow subtidal dominated by Microdictyon; intertidal
at Grass Island had large pathes of Neomeris; high
number and diversity of urchins and fishes.
Team: Bird surveys on Southeast Island. Weeding.
