KORAALRIFFEN WALLPAPER

This particular coral shape may be related to swell-generated currents that push free-living coral fragments over the shallow sea floor. As a native of Saba, it was a pleasure to experience the Saba Expedition with new faces and various goals for the week. Camping under water II. Een mogelijkheid om, zij het in een ondersteunde rol, weer eens wetenschappelijk te zijn. Nurse sharks did not really bother our presence and activities.

Fancy equipment was launched from the Caribbean Explorer II liveaboard followed by a bunch of brave divers and crew. A tale of many corals. Een mogelijkheid om, zij het in een ondersteunde rol, weer eens wetenschappelijk te zijn. Some of that was cleared away into tall, towel-covered piles to make place for our super fancy optical alkalinity titration setup. A disk-shaped corallith at Saba Bank Photo: We kept the tents and other equipment in for several days and hope for a smashingly exciting data set.

On another note, this was not the only thing that kept us busy on the Caribbean Explorer II for the past week. Nobody has been doing this in such a setting before as far as we know. Bringing any more electronics than your underwater camera means you’ll be working in the mess locally referred to as the dining room between meals. See us next time Saba Bank!!!

Een beetje vroeg, maar goed, een rondje door klein Amsterdam -een inwoner vergeleek Sint Maarten met Amsterdam vanwege het bijna identieke aantal nationaliteiten- en het was lunchtijd. And that’s how I kkraalriffen myself taking turns with colleagues Alice and Didier titrating and bubbling colorful little pots of seawater in a lab too small to fit a chair, but no less happy about it all.

However, coralliths belonging to the genus Madracis were not ball-shaped as regular coralliths but disk-shaped, similar to many species of mushroom corals in the Indo-Pacific. De Sababank bestaat namelijk uit een volwassen rif en geen zand.

Camping under water II. It is known as an aggressive invasive species in Brazil, where it competes for space with local, endemic coral species. We are now on our way back to St Maarten and I am deeply relieved that we came all out safe and healthy.

Hoeksema Naturalis Biodiversity Center, Leiden, The Netherlands Thursday 29 October The original aim of the coral diversity survey was 1 to find out whether the coral fauna of Saba Bank matches the coral fauna of St Eustatius and 2 to check whether the Saba Bank coral fauna has remained the same over nearly half a century by a comparison with results of an earlier marine biodiversity expedition to Saba Bank, which was organized in by the Dutch Navy and Naturalis.

Spot, ook wel Gorby genaamd vanwege de opvallende vlek op zijn hoofd was een vaak geziene gast. Some of the encountered coral species showed morphological variation by being either attached or free-living.

Koraalriffen by Mare Van Hessen on Prezi

Imagine you are tossed back and forth over the koraalriffsn calcareous reef bottom and try to take your underwater samples at m depth or get heavy equipment down to do it for you, or put up a tent. The corals are also exposed to coral-eroding organisms such as parrotfish or sea urchins.

Ondertussen maakte ik kennis met de populatie verpleegsterhaaien aldaar. Tijdens de lunch maak ik kennis met een aantal mede-expeditieleden. De dag werd begonnen met een tocht richting de Sababank, waar mijn werkzaamheden zich zouden focussen op het opzetten van koraalriffenn tent. In de namiddag ging de eerste poging tot het opnieuw opzetten van de tent dan ook verkeerd.

These graze for tasty algae or dig holes and grind away the calcium carbonate. In de middag, rond een uur of drie zouden we opstappen.

Een dag voor we aan boord zouden gaan worden we geacht dat we op Sint Maarten zouden zijn. G oPro time lapse came up really well with a successful deployment of the tent in Ladder Bay, Saba. Het assisteren bij de onderwaterwerkzaamheden. Coral fauna of Saba and the Saba Bank.
