Coral Reef Survey
Reef SurveyingKinds of scientific surveys
The reef is undergoing research to assess its reef integrity and resistance. We have a complete crew of science scuba diver at each dive site to perform these tests to obtain the most precise science available. It will help government, environment officers and communities better understand their coral communities so that they can better administer and conserve them.
To get a full view of reef sanity, researchers need to study the whole reef system, not just one single one. At each reef we see, we carry out coral, soil or bedrock and fishing investigations. Coral survey is to measure the magnitude, nature and condition of each coral along a tranect, which allows an exact evaluation of the coral population on each reef.
In the course of the prophylactic examination, every few metres a note is taken of what is on the reef floor to establish how much room each organisms occupies on the reef floor. Pisces are examined in a similar way, with the diver recording the height, the type and the number of all fishs they see in front of them.
So we know how sound the fishing communities are and what kind of species of fish interact with the reef. All of these explorations are repeated in several places and at different levels of depth as we travel from islands to islands and conduct our marine research. Doing the same research on each dives with the same method, we are able to reconcile our observation from one place to another.
We can see the difference in reef sanity and resistance between locations, cliffs, islands and even states.

Introduction of the coral reef survey approach. What makes you think a scientist wants to measure the number of species on a coral reef? Ask your pupils to think about the number of species, the number of species and the reef's healthy condition. Tell your pupils that knowledge of the number of species living in a small part of the reef can help researchers to assess the abundance of the reef's total fishmonger.
For the researchers it is important to look at the different kinds of seafood. The diversity or number of specimens in a given area is information that researchers use to determine whether a coral reef is sane. "Present the tape by letting your pupils know that Enric Sala and his scientific staff are investigating and documenting the coral cliffs of Flint Island and dive up to 50 dives a full-day to gain a full understanding of this maritime erythm.
Present the videoclip to the pupils. Ask: 3. introduce and describe different kinds of fishing survey techniques, concentrating on the Belt Transect (BLT) approach. Tell the pupils that there are a number of ways to try some of the different kinds of music: for example: Tell the pupils that they will be simulating the Belt Transect (BLT) methodology in the schoolroom.
On the blackboard, paint how you describe the BAT to give the pupils an image they can allude to. Declare that two tracks with three cables are produced during a survey by means of a BAT. Scuba diver are swimming in the same way and observing the species they see in their alley. When they first go swimming, their alleys are four metres across and they are looking for catches taller than 20 centimetres.
On the second occasion, the alleys are two metres across and they are looking for less than 20 centimetres of game. Scuba diver also make sure they look for hidden reef spurs and cavities. Let the pupils ask you about this fishing survey methodology.
Conducting rehearsals of seafood in the schoolroom. Describe an area of 10' x 10' or 100 sq ft of the room. Distribute a pre-determined number of fishing cut-outs in this room. Divide the pupils into ten small groups and ask each group to name one pupil as the datographer. For each group, give a 1' x 10' section of the 100 sq ft area.
Let the pupils in each group of pupils score the six inch tails to the right and six inch tails from their transex line. Give the pupils enough ample space to carry out the check. Let the student analyse the gathered information. When all groups have completed enumerating them, have each group guess the number of species they believe to be in the 100 sq. ft. range on the basis of the number of species they have enumerated in their 1' x 10' section.
Please ask them to sign their cost estimates with their personal details. Once the pupils have made their assumptions, you ask: How many have each group counted? Then, let the pupils work out the real number of the 100 sq. metres of the area. What was your estimation compared to the real number of species in the 100 sqm area?
Did you make a good guess or not? How does that tell you about the importance of taking samples for testing your cat? Conclude by debating the parallels and discrepancies between the BAT methodology in the schoolroom and a true BAT survey conducted by oceanologists. Pupils should for example realize that a true study of aquatic life is a greater challenge, as both scuba diver and aquatic life are constantly in motion and can be hidden from them.
