Aug 31, 15     Comments Off on Smithsonian Explores Klein Curacao in a Sub

Good morning friends, how was your weekend out there?? I apologize for the lack of postings lately but we have been super busy playing with the folks from the World famous Smithsonian Institution. Last wednesday was spent taking load after load of supplies to the Chapman (the white ship seen in the 2nd photo) and getting ready to set sail for the remote island of Klein Curacao early thursday morning. The top photo shows our 2.5 million dollar mini submersible named the “Curasub” on the back of the research vessel the Chapman heading out to sea on the way to Klein Curacao. The second photo shows the Chapman anchored at Klein Curacao and the bottom photo shows the view of the desolate island from way above the Chapman, both of these killer shots are compliments of our sub pilot Barbara who has a mini-drone and boy does she know how to use it! Check out her link below and be sure to “like” her page as we greatly appreciate the use of the photos.

So once we arrived at Klein Curacao we first lifted our giant floating platform into the water with our onboard crane and once that was in place and tied up the sub was next. Once the sub is in the water and in the floating dock we do a bunch of last minute checks and then toss in some scientists and off we go to the abyss. Every time the sub took off I jumped in the water with camera in hand and did a fun photo shoot underwater of it’s passengers and once that was over I used up the rest of my air exploring my new underwater world. I have a bunch of new photos to send you that I took while the sub was deep below exploring the darkness in search of new and exciting finds. Back on the ship I had two aquariums running filled with very cold water ready to photograph any and all new finds the Smithsonian might return with. The sub was usually gone for around three hours at a time giving me and many of the others onboard time to either go diving, snorkeling, exploring the island, or as many did, just grab a book and a drink and kick back in the warm tropical sun. In the two days we were on the island the Smithsonian did four submersible dives bringing back many finds for yours truly to photograph and yes, I will be sending those as soon as I get them ready. One of my favorite finds was a small, strange looking hermit crab living inside a live anemone, you have to see it to believe it. Other items I loved included a super weird giant sea-cucumber with a bright red foot, a beautiful long spined sea urchin with crazy colors and another fish that will blow your mind. Beside fish and creatures they found all kinds of beautiful antique bottles from the 1800’s and all the bottles were filled with small shells that most likely crawled in but couldn’t get back out, bottles are a death trap for many crustaceans. On my fun scuba dives I saw turtles and rays and some of the best looking brain corals I had seen in a long time, this is such a great spot to go diving it’s just a long ways a way!

We are all busy this morning cleaning and putting stuff away, I have to get back to work…

Have a wonderful day and stay tuned for more.

Aug 26, 15     Comments Off on Yellow Pencil Corals, Madracis auretenra

Hi all, we are having a super busy day getting ready for our two day trip to Klein Curacao with our sub and lots of VIP’s. I just got back from the ship, I took a whole car load of diving gear and camera stuff over and that is just my stuff. I think we are taking around 60 tanks this time, there will be non-stop diving on this trip so I should have a ton of new photos for you on monday.

Here is a beautiful colony of Yellow Pencil Coral or Madracis auretenra that we have at 50 feet out in front of our lagoon. This is one of the last colonies we have that has not been destroyed by our local fisherman and their careless anchors. These colonies are home to countless fish and creatures and it’s a favorite coral for juvenile trunkfish, one of our all time favorites.

Madracis auretenra, commonly known as yellow finger coral or yellow pencil coral, is a colonial species of stony coral in the family Astrocoeniidae. It is a fairly common species and is found in the Caribbean Sea and Western Atlantic Ocean. At one time this species was not recognised, but it was split from Madracis mirabilis on the grounds of morphology and depth range.

Pencil coral forms hemispherical clumps that can be a metre or more across. Each colony is formed of densely packed, cylindrical branches with blunt, finger-like tips. In fore-reef habitats the branches are slender but in back-reef and lagoon habitats they are more robust and the clumps are larger. The hard skeletal material of which the colony is built is in most coral species covered by a thin layer of living tissue, the coenosarc. This coral is unusual in this respect because, as the coral grows, the coenosarc progressively dies back on the lower parts of the branches leaving the skeleton bare, and only the tips of the branches are covered with living tissue. The corallites are from 1.1 to 1.6 mm (0.04 to 0.06 in) in diameter and have at least ten septa.

Pencil coral is a zooxanthellate coral, housing symbiotic single-celled protists within its tissues. These provide the products of photosynthesis to the coral and use some of the coral’s waste products. To supplement this food supply, the coral polyps spread their tentacles to catch zooplankton, feeding mostly on the larvae of crustaceans, polychaete worms and arrow worms.

Pencil coral is a hermaphrodite; individual colonies contain both male and female gonads. Liberation of gametes into the sea is linked to the phase of the moon and other factors. After fertilization, the planula larvae form part of the plankton and eventually settle on the seabed and undergo metamorphosis into polyps. In some instances, M. auretenra has been observed to retain the gametes on its mesenteries and pseudo-brood the larvae briefly before liberating them into the sea.

Pencil coral also reproduces readily by fragmentation, a form of asexual reproduction. Even quite small fragments of the coral are able to survive and grow into new colonies; survival rates in trial studies varied between 29 and 81%, with the rates being highest in fore-reef environments and lowest in lagoons where there were higher levels of sedimentation.

Pencil coral has been used as a study organism to predict the effects of ocean acidification on corals. By manipulating the composition of modified sea water in which the corals were kept, it has been shown that the carbonate or aragonite concentration of the water, the factor usually considered as important predictors, was less relevant than the bicarbonate concentration.

I have to run, have a wonderful week, see you on monday…

Aug 18, 15     Comments Off on Curacao Dive Sites, Playa Forti West End Beach

Good morning friends, I had a request asking about diving at Playa Forti. For those of you not from here, Playa Forti is a beach located near the village of Westpunt on the north-west side of the Island. The quaint little beach has sheer cliffs on one side and a crystal clear ocean on the other and it’s always super calm water. There are steps leading down to the beach which is covered in small pebbles and a snack bar and restaurant at the top. Close to the restaurant, there is a spot where you can make a 10 meter (over 30 feet) jump from a cliff into the sea. I did it once and my buddy Leon did a full out swan dive off this thing, to say he surprised us all that day would be an understatement! Diving here is really great, the single only downside is carrying your dive gear up and down the 30 foot of stairs, it’s similar to 1000 steps in Bonaire but not near as steep! The first thing you will encounter once underwater is sand and lots of it, in fact you can see at least 100 feet in every direction and it’s just sand! But sand is great.. There are countless creatures and fish that love sand that you may not see in other dive spots like the beautiful flying gurnards, those alone are worth the trip. We also commonly spot turtles and rays not to mention eels and all kinds of crabs, I really think you will love this spot! After about 10 minutes of swimming straight out towards the reef you will start to encounter these lone outcrops of corals and sponges like you see above and trust me when I say you could spend a whole dive just looking at these as they are covered with life!

I TRIED to fly to Miami on Sunday to pick up my new bike but once again good o’l American Airlines had mechanical issues and they were grounded! We all sat there for hours waiting, seven to be exact and it still never left, I finally gave up and called Aimee to just come get me, what a joke. I am going to try again tomorrow, we will see….

Lots going on, I have to run.

Aug 10, 15     Comments Off on Sea Grape Leaf, Leaf Venation, Tropical Leaf

Good afternoon friends, guess what???? It’s been raining!! We have had at least four great downpours in the past week, our island is once again going from dry brown to lush green almost overnight and we are all loving it! Because of all this new wet stuff we found a new frog that we have never seen before and of all places we found him high up on our balcony!? I will try and post those tomorrow he or she is super cute!

I have a bright green sea grape leaf for you all today that I shot outside my window for you all, I just thought it was pretty with the way the sun was shining through it lighting up the little veins.

The veins are the vascular tissue of the leaf and are located in the spongy layer of the mesophyll. The pattern of the veins is called venation. In angiosperms the venation is typically parallel in monocotyledons and forms an interconnecting network in broad-leaved plants. They were once thought to be typical examples of pattern formation through ramification, but they may instead exemplify a pattern formed in a stress tensor field.

A vein is made up of a vascular bundle. At the core of each bundle are clusters of two distinct types of conducting cells:

Xylem: cells that bring water and minerals from the roots into the leaf.

Phloem: cells that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf.

A sheath of ground tissue made of lignin surrounding the vascular tissue. This sheath has a mechanical role in strengthening the rigidity of the leaf.

The xylem typically lies on the adaxial side of the vascular bundle and the phloem typically lies on the abaxial side. Both are embedded in a dense parenchyma tissue, called the sheath, which usually includes some structural collenchyma tissue.

I bought a used 2013 Carbon Specialized Epic, it weighs a tasty 21 pounds!! I have to fly to Miami this Sunday to pick it up, the guy is bringing it to the airport for me. The Epic I have now weighs close to 30 pounds, I’m plain sick of pushing all the unnecessary weight!

Busy day….

Later, Barry

Aug 7, 15     Comments Off on Finding Mangrove Seeds and Replanting Them

Good morning friends, Aimee and I have been busy at Saint Joris bay for the past few weeks doing our part to encourage new mangrove growth by picking up the seeds and replanting them in the mud, it’s super fun! Photo #1 shows a small section of the beautiful mangroves and the area we are currently planting in. Photo #2 shows hanging mangrove seeds before they fall into the water. Photo #3 shows mangrove seed pods washed ashore waiting for us to find them and plant them. Photo #4 shows the seed pods we picked up in just a few minutes, they are everywhere and not hard to find. Photo #5 shows the pods being stuck down into the mud. Photo #6 is Aimee with her screwdriver in one hand and a pod in the other, I think we planted around 100 here. The last photo shows how the seed pods grow once stuck in the mud.

In this harsh environment, mangroves have evolved a special mechanism to help their offspring survive. Mangrove seeds are buoyant and are therefore suited to water dispersal. Unlike most plants, whose seeds germinate in soil, many mangroves (e.g. red mangrove) are viviparous, whose seeds germinate while still attached to the parent tree. Once germinated, the seedling grows either within the fruit (e.g. Aegialitis, Avicennia and Aegiceras), or out through the fruit (e.g. Rhizophora, Ceriops, Bruguiera and Nypa) to form a propagule (a ready-to-go seedling) which can produce its own food via photosynthesis.

The mature propagule then drops into the water, which can transport it great distances. Propagules can survive desiccation and remain dormant for over a year before arriving in a suitable environment. Once a propagule is ready to root, its density changes so the elongated shape now floats vertically rather than horizontally. In this position, it is more likely to lodge in the mud and root. If it does not root, it can alter its density and drift again in search of more favorable conditions.

Mangroves are various large and extensive types of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics—mainly between latitudes 25° N and 25° S. The remaining mangrove forest areas of the world in 2000 was 53,190 square miles (137,760 km²) spanning 118 countries and territories.

Mangroves are salt tolerant trees (halophytes) adapted to live in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen (anoxic) conditions of waterlogged mud.

Lots to do, have a wonderful weekend!!

Aug 4, 15     Comments Off on Invasive Lionfish taking over the Caribbean

Good afternoon all, we just loaded our 6 ton, 2.5 million dollar submersible onto a flatbed truck for it’s journey over to our research ship called the Chapman where it will be loaded onboard for it’s early morning voyage tomorrow. The plan is to take the sub to our little island of Klein Curacao and do a pre-run of sorts before the Smithsonian Institution arrives later this month, we want to make sure the ship is in tip-top running order. I am unable to go on this trip due to my broken hand and not being able to get the cast wet so I will hold down the fort here at substation.

This is one of my resident lionfish that lives at around 110 feet out in front of the Substation lagoon and I try to stop and say hi every time I am out. There are a few lionfish here that everyone knows not to mess with as I photograph them on a daily basis and they have become very docile and super easy to approach, kind of like fish friends if you will. Some of these fish are so used to my presence that they will swim right up to the camera and just hang out there without a care in the world, I will have to do a little video for you. Speaking of video I got a new Go-pro 4 for my b-day way back in July and am waiting for the macro lens and card to arrive later this month, then I can start posting more fun videos for you.

Well, lots to do, I have to run…. Oh yeah, we got a nice rain this morning, it was fantastic!
