8/21-22/2019 - Data Logger Deployment

Laura and Marc went down to Wailea Bay at 0900 h on Wednesday (8/21/19) and deployed two salinity / temperature data loggers in about 2 m of water near living small Pm coral heads.  The data loggers are set to record salinity and temperature every 5 minutes.
Marc went down and deployed data loggers 3 and 4 at 1100-1130 h on 8/22/2019.  The water was much calmer and visibility better on 8/22.. surf was down to near 0'. 

Location of data loggers 1 and 2 deployed at Wailea Bay on 8/21/2019 at 0945-1045 and data loggers 3 and 4 deployed at Wailea Bay on 8/22/2019 at 1100 h and 1120 h..  Loggers programmed to record salinity and temperature every 5 minutes.

Data Logger 1:
Deployed at 0945 on 8/21/2019 in ~ 2 m of water attached to a dead Pm coral head on a large basalt rock
Salinity at deployment site = 35 ppt
Water Temperature at deployment site = 28 degree C
South swell running at occasional 3 foot
Water murky with fine sediment stirred up by wave action.
Data Logger 2:
Deployed at 1015 on 8/21/2019 in ~ 2.5 m of water attached to a dead Pm coral head on a large basalt rock
Salinity at deployment site = 35 pp
Temperature at deployment site = 28.5 degree C
South swell running at occasional 3 foot height
water murky with fine sediment stirred up by wave action.
Many of the young Pm coral showed signs of bleaching.
Data Logger 3:
Deployed at 1100 h on 8/22/19
Data logger Wailea 3 deployed at 1100h on 8/22/2019 in ~ 3 m of water attached to a dead Pm coral head on edge of basalt island
Salinity = 33 ppt
Temperature = 28.5 degree C
Water calm, visibility 10 m
Data Logger 4:
Data logger Wailea 4 deployed at 1120 h on 8/22/2019 in ~ 2 m of water attached to a dead Pm coral head
Salinity = 33 ppt
Temperature = 29.5 degree C
Water calm, visiblity 10 m

Site 5:  19.980444°, -155.829568° - took water sample in 1.5 m of water - salinity = 32ppt, temp = 29.5 ⁰C at 1130 h , 8/22/2019.  Surface water temp = 29.5 ⁰C (note: water was calm, 5 kt onshore wind and medium visibility (10 m).

Number of people at beach along Wailea Bay between 1200-1215 h on 8/22/2019 (black numbers) and in the water swimming and snorkeling during the same time interval (red numbers).

Below are some images of Pm colonies taken on 8/21/19 on the north side of the bay approximately 15 to 30 meters off shore in shallow water (2-3 m).

Short Survey of Wailea Bay searching for Coral Recruit Colonies

8/7/2019
1300-1400 H
I snorkeled a route around the rock island on the south side of the Bay adjacent to transect E, around the western tip of the island, back in toward shore and around the eastern end for a short distance.  My goal was to determine if there was any coral recruitment occurring in that area (as reported to Bill by Spielman).
I took photos of the new and fairly new Pocillopora meandrina  heads and a few Porites sp. as I came across them during the snorkel.

First part of transect E- the southern side of the rock island, as the video shows, is very "dead."  However, once I went around the offshore end of the island and came back towards shore I found quite a few new coral heads.  I am unable to estimate density but it is quite low, I am sure.   I have divided the images into two areas: 1.  the south side of rock island (the first part of transect E), 2. the north side and east end of rock island.

There were quite a few new colonies even in the shallow areas.  I can see where Mr. Spielman reported that there was some recovery.
The numbers are not large but they are there... the place isn't totally dead!

Area 1  -the south side of rock island (the first part of transect E)

Area 2 - he north side of rock island

I forgot... I took some pictures of the shower area also.

I was surprised to see this critter out in the open!
