End of Week 1

It's been a couple days since I have made a post, things have been quite busy here in Bonaire.

On Thursday I went diving with a group and an instructor named Albert on the eastern side of the island in Lac Bay at a site called Cai. Normally diving is not possible on the eastern side to to large waves and strong currents, however this time of year the waves are generally smaller, which makes diving easier. This was a fairly shallow dive, reaching a maximum depth of 59ft, which allowed me to accumulate a bottom time of 74 minutes. I saw my first sea turtle at this location. It was too far away for me to get a pictures, but was very neat.

This site also had many large sea fans.

There was also some large elkhorn coral formations here.

I met a man, named Jaap, from Holland, on this excursion that was here with his non-diving wife and was looking for a buddy. Him and I paired off and went on to do another dive in the afternoon at the far northern end of the island at Nucove. This was one of the nicest locations I have been to so far. The coral was fairly broken-up in the shallower areas, but was quite lush and vibrant in the deeper waters.

Friday, I went out in the morning with Edwin again on his boat to do some work with the drop camera. We again went out to Klein Bonaire to visit some of the deeper sites. After purchasing all of the necessary components to power the camera using the boat's battery I hooked it up and everything was working above water. I lowered it down seeing nothing but water. Once I had let out about 150ft the video changed to nothing and was since after useless. It still displays a fairly clear picture on the surface, but does not work underwater.

This is what the camera displays while underwater.

After failing with the drop camera, we decided to do one dive at a location called "The Cliff" which is one of the only reef walls around bonaire. We have some AUV data very close to this location, so I was able to get some good structure pictures here. There was also a small sea turtle that followed us for about 10 minutes.

It's difficult to tell due to the bad lighting, but this is a vertical wall.

In the afternoon, I did two more dives with Jaap, one at a place called "Angel City" and another called "Tory's Reef" These were both nice sites, however my camera battery was dead, so I don't have any pictures.

Today, Saturday, I went diving with Jaap again. He flies home tomorrow evening, so today was his last day to dive. We visited the Lighthouse at the southeastern end of the island, the waves were a bit chopping, making entrance and exit difficult, but the reef there is very healthy due to the low number of visitors that dive that site. The second location was called Red Slave due to its location near the slave houses at the south end of the island. I hope to make it back down there to get some on land shots this coming week. This island has quite an interesting history.

Klein Bonaire

Yesterday I went shore diving at three different sites with a man I met on the Bonaire Talk forums. We visited two sites at the south end of the island, including the Hilma Hooker, a 240ft shipwreck sitting in 100ft of water. Within the ship's hull we saw a large green moray eel. The last site of the day was near the northern end of the island, the reef was gorgeous and I will be making more trips up to that area in the following week. Being my first day diving I didn't want to worry with dealing with a camera and I just enjoyed the sites and got used to the area.

Today I visited two of my research sites on Klein Bonaire. It did not occur to me that most boats here would not have a standard electrical outlet, like the research vessels that I'm used to, so I was unable to make use of my drop camera. I have since purchased an inverter that can be hooked up the the boat's battery and I will be taking the drop camera out on Friday. I was however able to dive on two of the sites and photograph the morphology in the shallower locations. Both reefs appeared healthy.

Site 1:
"Just a Nice Dive"

We reached 110 ft maximum depth on this dive, and this is my deepest lifetime dive. It was pretty exciting. There was still plenty of light at that depth due to the high clarity of the water.

Here you can see the steep slope of the reef and that it completely covers the bottom. (30m depth)

PA270036.JPG
There were also many noticeable breaks in the reef that could be identified as slumps in deeper depths (25m depth)

PA270048.JPG
As expected, coral was more sparse in shallow depths (8-10m depth)

Site 2:
"South West Corner"

The reef at this site was very different that the first location of the day, due to it's location on the other side of the island. This site actually has two reef layers with one in shallow water and the second starting at 160ft. This can easily be seen the the data collected by the AUV. We only dove on the shallow part but I hope to revisit this site with the drop camera on Friday.

Figured I should get a picture of myself.

This site had the lushest and healthiest reef of any of the sites I have been to so far

Sunday

Besides the Dive Shops and a few restaurants, the island pretty much shuts down on weekends. This morning I walked over to the Dive Friends Yellow Sub Dive Shop to obtain my STINAPA marine park pass and do a check out dive. It's nice to be able to dive with so much less lead than what i'm used to in the North Atlantic. I'll be storing my gear at Yellow Sub for the week so that I don't have to keep trekking it back and forth from the apartment

After lunch I headed out to do some snorkeling.

Scuba Diver (Homo sapien) He took a picture of me too.

PA240019
To the best of my knowledge this is some species of rope sponge. It was in 30+ ft of water so I couldn't stay real long to investigate.

Arrival

Welcome to Bonaire

I arrived in Bonaire around 14:00 today in the midst of a mild rain storm, but it ended quickly. The temperature here is close to 90° F. I had no problems catching any of my flights and customs was a breeze.



Flamingo Airport



The place I'm staying at is exceptional. Caren Eckrich, one of the CIEE members provided me shelter in her guest house. I could no be happier. Tomorrow I'm planning to take care of the necessary measures to go diving.



My house for the next two weeks.

CIEE Public Lecture

I will be working alongside the CIEE research team while in Bonaire and will be giving a public lecture on November 4, 2010.

2 Days To Go

In less than 48 hours i will be on the ground in Bonaire, assuming that I make all of my flights.  For those of you that don't know, Bonaire is a small island in the Southern Caribbean, and the site of my Master's Thesis work.  Bonaire is commonly known as a "Divers Paradise" and says so right on their license plates.


The University of Delaware conducted an AUV survey of the island in January of 2008 mapping many of the offshore reef sites.  I have been processing and analyzing this data for over a year and have never had the opportunity to visit my field site. As of Saturday, October 23rd that will all be changing.  I am traveling to the island for two weeks to perform ground-truthing of some of the shallow survey sites.  I will be using an Olympus underwater camera with an Ikelite Autoflash AF35 strobe attachment and a drop camera with a 300ft cable.

I'm planning to update this blog as regularly as possible while I'm away, but I'm not sure what my internet situation is going to be, so that may be a limiting factor.  Enjoy!

Finally, to make you jealous, here is the view that I will be enjoying for the next two weeks.
