AGRRA Rep 7 (Extract)
Date of Observation: 2/8/2023 Submitted 2/12/2023
Reef Type: Fore Reef
Avg Depth 3 m (estimated)
Water Temp 24 (estimated)
Reef Name: Vauxhall
Location:
Reef Type: Fore Reef
Survey Observations What did you observe during the survey? (Check all that apply): Healthy Corals
Survey Protocol: Snorkelling, Location by camera GPS above water. Depth, temperature are estimated
Describe Observed Disease/Bleaching: I attach 2 photos of healthy pillar corals at this location. Pillar corals are fairly common on this reef, I have seen no sign of any disease on them. I assume this is of interest as I understand Pillar Coral is Highly Susceptible to SCTLD; I have submitted reports of other species on this reef with presumptive SCTLD

AGRRA Rep 9 (Extract)
Date of Observation: 2/12/2023 Submitted2/15/2023
Reef Type: Fore Reef
Abg Depth 3 m (estimated)
Water Temp 22 (estimated)
Reef Name: Reef # 33 in Folkestone MPA (Barbados)
Location
Reef Type: Fore Reef
SCTLD Observations: Corals with stony coral tissue loss disease
– M. cavernosa 1-5 colonies
– P. strogosa 6-25 colonies
– Siderastera siderea 1-5 colonies
Survey Protocol: snorkeeling along seaward edge of fringing reef
Describe Observed Disease/Bleaching: Snorkelled edge of Reef #33 (see ap in photos), total of 11 OICs (Obvioulsly Infected Corals), 8 were P. strigosa with presumptive SCTLD, one was S. siderea with Dark Spot, one was S. siderea with presumptive SCTLD and one was M.cavernosa with premumptive SCTLD. There is not a great abundance of corals along this reef, prob due to storm water outfall, guess circa 150 total over this route

AGRRA Rep 10 (Extract)
Date of Observation: 1/27/2023 Submitted 2/13/2023
Reef Type: Other
Avg Depth 6 m (estimated)
Water Temp 24 (estimated)
Location
Reef name: Area of Fringing Reef #31 (Maclean& Oxenford, 2016) in Folkestone MPA
Reef Type: Other – A route from nearshore breakwater to forereef area by reef #31 back to edge of fringing reef #32
Coral Health Survey Observations: health Corals, Corals with SCTLD
P. strigosa 6-25 colonies
Survey Protocol: Snorkelling, positions approximate
Describe Observations: 3 photos of corals, all appear to be D. strigosa, with premsumptive SCTLD. There were many of these on the nearshore breakwater at Pos A. On the rest of the route, only 2 more infected corals observed, one offshore circa 6 m depth (Pos B), final one (Pos C) at edge of fringing reef perhaps 2.5 m depth. There are not many corals in offshore area, quite impacted by silty runoff from big storm sewer, also nutrients from onshore fish processing

AGRRA Rep 12 (Extract)
Date of Observation: 2/5/2023 Submitted 2/14/2023
Reef Type: Fore Reef
Avg Depth 6 m (estimated)
Water Temp 24 (estimated)
Reef Name: Vauxhall
Reef Type: Fore Reef
Coral Health Survey Observations: Healthy Corals, Corals with SCTLD
Diploria labyrinthisformis, 1-5 colonies
O. Annularis, 1-5 colonies
P. Strigosa, 6-25 colonies
Survey protocol: snorkelling
Describe Observed Disease/Bleaching: These sites are on a track that went from just beside “The Wreck” (position A in photo) which is popular with snorkelling boats and a site of many infected corals as previously reported, south tp Pos B by another piece of the wreck (with fewer corals, not frequented by snorkelling boats0, and then further south to a permanent mooring./surface float. The predominant current is southwards. There is a lot of O. annularis here about 6 m depth, it seems uninfected except on a specimen at Position B (in photos). In total there were 7 sites where there were clusters of infected corals, a few places where just one coral was infected (presumptive SCTLD), mostly it appeared, P. strigosa.

Describe Observed Disease/Bleaching: I swam the edges of 2 adjacent fringing reefs as shown in first photo, depths 1 to circa 5-7m. These are highly degraded reefs, very low coral cover and most of what’s there doesn’t “look healthy” but few with overt disease except: 3 P. strigosa with presumptive SCTLD, (2 in photo), 1 D. labyrinthiformis possible SCTLD, and 1. M. cavernosa with presumptive SCTLD.

Repeat observations of same corals examined on Jan 21, 2023. Both sets of photos shown.Ist coral by sea-fan I am calling P.clivosa, but needs confrim (not P. strigosa?)

AGRRA Rep 21 (Extract)
Date of Observation: 3/8/2023 Submitted 3/9/2023.
Reef Type: Fore Reef
Avg Depth 7 m (estimated)
Water Temp 24 (estimated)
Reef Name: Vauxhall

Species: O. annularis
Protocol: Snorkelling: Snorkelling, water temp and depth estimated
Comments: A comparison pics show one colony of O. annularis on Feb 5, 2023, and again on Mar 8 2023. Another photo is a closeup of the disease front on Feb 5, 2023 and appears to show a zone of sloughing off tissue. Finally a photo shows the dense colonies of A annularis in this area on Feb 5. I have been keeping an eye out for infected O annularis, this is the only one I have seen that looks like SCTLD; 99%+ of the colonies in this area and closer to shore remain free of disease
