A project by UC Berkeley is mapping all the dangerous beaches in the world. Beach Hazards include geology, surf, marine organisms and pollution. A bit disturbing:

interesting project, especially as a multivariate mapping project. however, at least for the hawaiian islands, their data is so incomplete it is really irresponsible to publish a hazard map that really misleads people as to what the hazards are.

They have certainly highlighted problem areas but I have to agree with Rob about the lack of data. The California Coast as shown is missing a huge amount of info. A sad part of this is that the project is based at Cal Berkeley.

I think the effort is valid and states its assumptions and rules for classification up front.
As a water resource consultant in California, I agree with its 'water pollution' hazards primarily in the south coast where the cities and stormwater and wastewater treatment plants are. The central coast is largely without large urban areas, so other hazards might be spotty (sharks, currents, etc.).

Having traveled a little, I would add more hazards along the coastline of the Mediterranean, as there are many cities with direct untreated wastewater discharge to the sea, olive oil plants, and stormwater runoff - so lots of dirty water in the mild, shallow, surfzones - it can be nasty. Would suppose same for all urban/coast interfaces, including India, China...

I think the project could grow to be quite useful to the gen public.

It also does not appear that for each hazard indication there is a study(s) with well collected data where the user would 'drill down' to the reports etc. Again, their rules and assumptions are safe and would generally be supported in the literature.
