Hi,

I'm doing a master in marine ecology in the french 'Research and Development Institute' (IRD).

I’m working on island connectivity in the Mascareignes Islands (South-West Indian Ocean).

For this, I’m trying to modelise reef fish larvae transport.

I’ve different environmental data : geostrophic currents from Aviso, SLA , SST and Chla. However, biologically I don’t have any data about fish larvae density or anything, just the place we collected larvae and the pelagic larval duration. With these informations I think I can guess the place where larvae have been released out of the reef.

 

I was thinking, in the first hand, to study the transport with geostrophic currents only and see if there is any possible connectivity between islands. Then I’d like to precise this with SST, CHLa and SLA data.

 

I’ve install and play a bit with MGET toolbox and ArcView 9.3. I couldn’t try every tool because I’m waiting for ArcInfo licence.

Apparently the tool for analyzing connectivity networks is under development. Do you think I could adapt the tool for analyzing coral reef connectivity by simulating hydrodynamic larval dispersal? In that case I would presume that fish larvae are passive like coral larvae.

Or do you think in another way I could use MGET to realise my study?

 

Thanks for your help,

I would be pleased to collaborate with you in the future,

Best regards,

Estelle Crochelet
