My Final Year Project (IIUM 2010)
"Suspended Sediment Effects towards Coral Ecosystem in Pulau Redang"
by
Muhammad Faiz bin Mohd Hanapiah
Supervised by
Dr Shahbudin bin Saad
Overview
One of the major stressors on corals is the settlement of suspended sediment on their surfaces. This leads to blocking of light, smothering of the coral mucus surface and increased risk of disease. Sedimentation rate on a reef is highly important variable in studies of coral reef. The level of suspended sediment in marine environment is increasing due to development of coastal area and also recreational activities in the coral reef. Research on sedimentation rate is often done by deployment of sediment traps, containers positioned vertically with an open top and capped base. These remain submerge for a period of time before they are removed and the sediment collected in the containers dried and weighted as a quantifiable measurement of sedimentation on the reef.
May Allah give me strength to make it a successful one..
little bit info about Department of Marine Park Malaysia
The department of Marine Park Malaysia, of the Ministry of Natural Resources and Environment (NRE) was officially established on 16th July 2007. Formerly known as the Marine Park section under the administration of Department of Fisheries, the section was later transferred to NRE. Marine Park Malaysia or MPM, as it is now commonly known, is responsible for managing the marine parks of Peninsular Malaysia.
Objectives:
- To conserve and protect the biological diversity of the marine community and its habitats.
- To upgrade and conserve the natural habitats of endangered aquatic species.
- To establish management zones for the conservation of aquatic flora and fauna.
- To establish zones of recreational use consistent with its carrying capacity.
- To manage and develop capacity building in public awareness programmes.
gedebush!!!
tomorrow gonna be the pool session
one step in scuba diving
againsts all fears
againsts all worries
nervous and bla2..
"jgn pikir, terjun je!!"

dinoflagellate
What are dinoflagellates?
Dinoflagellates are microscopic, (usually) unicellular, flagellated, often photosynthetic protists, commonly regarded as "algae" (Division Dinoflagellata). They are characterized by a transverse flagellum that encircles the body (often in a groove known as the cingulum) and a longitudinal flagellum oriented perpendicular to the transverse flagellum. This imparts a distinctive spiral to their swimming motion. Both flagella are inserted at the same point in the cell wall, by convention defining the ventral surface. This point is usually slightly depressed, and is termed the sulcus. In heterotrophic dinoflagellates (ones that eat other organisms), this is the point where a conical feeding structure, the peduncle, is projected in order to consume food.
Dinoflagellates possess a unique nuclear structure at some stage of their life cycle - a dinokaryotic nucleus (as opposed to eukaryotic or prokaryotic), in which the chromosomes are perminently condensed. The cell wall of many dinoflagellates is divided into plates of cellulose ("armor") within amphiesmal vesicles, known as a theca. These plates form a distinctive geometry/topology known as tabulation, which is the main means for classification.
Both heterotrophic (eat other organisms) and autotrophic (photosynthetic) dinoflagellates are known. Some are both. They form a significant part of primary planktonic production in both oceans and lakes. Most dinoflagellates go through moderately complex life cycles involving several steps, both sexual and asexual, motile and non-motile. Some species form cysts composed of sporopollenin (an organic polymer), and preserve as fossils. Often the tabulation of the cell wall is somehow expressed in the shape and/or ornamentation of the cyst.
Why bother?
Besides being important primary producers, and therefore an important part of the food chain, dinoflagellates are also known for producing nasty toxins, particularly when they occur in large numbers, called "red tides" because the cells are so abundant they make the water change colour. Besides being bad for a large range of marine life, red tides can also introduce non-fatal or fatal amounts of toxins into animals (particularly shellfish) that may be eaten by humans, who are also affected by the toxins. Many of these toxins are quite potent, and if not fatal, can still cause neurological and all sorts of other nasty effects. Add this to the rather ominous suspicion that red tides may be more common thanks to human inputs of phosphates and warmer global temperatures, and you can probably see why we have a vested interest in finding out more about them - both medical and economic.

Lab session in UKM
We are actually having marine microbes lab session in UKM starting today.it was tiring
full of moving here and there
overloaded with lecture on dinoflagellate
and lab work...
phew..
to all other marine guy
be strong... be fresh...
earn these moments.....:-)
