the gambia is a small strip of low lying land in west africa. as one of the world s poorest and least developed countries, it is suffering the effects of a climate crisis it did little to cause. climate change activists fear that unless concerted action is taken soon, disaster looms. we re facing high temperature rises, less rainfall is changing the whole rain pattern, and we re looking at the mangroves dying due to high salinity rises. so what we re looking at, how do we find maybe scientific models or industrial models or equipments that could be able to help people track the salinity level in these rivers that could be able to guide our planting processes. but oysters are not only used to make traditional dishes like oyster stew, but the shells are dried for a year and used as paving around fishing towns, driveways and also used to make paint and chalk.
characteristics of deep water. and they present some real challenges. among them, something called the sound fixing and ranging layer. this is about a half mile down. it s a naturally occurring portion of the water where sound travels less quickly than it does below or above. a lot of different reasons. the salinity level, water temperature, and this is the result. sometimes because of this layer, a sound that may come up out of here can hit that slower area and be bent at a very substantial angle, so when it emerges, it s quite different from where you would expect it to be. in other cases, sound may come up out of here, and when it hits this layer, it can start ping-ponging between the top and bottom parts of it, and can actually go on, it s believed by researches, many miles before it resurges resurfaces. so in effect, that could explain why a pinger that should only be heard for about three miles, in the best of circumstances, may
