Funafuti

Extreme High Tides, 2007

Funafuti is a place where the tide rises through the ground because the atoll is deeply fissured and shattered. With the extreme tides in January and February, tide peaks are preceded by rapidly seeping sea water rising through and flowing across the sandy atoll soil. At lower places on the atoll, some of which were once swamps, paths, roads, gardens, and homes can be flooded, and, if they are not rescued from their pens, pigs can drown. At this point on south eastern Funafuti, sea water seepage can be ankle to knee deep and stays for hours after the tide peaks before seeping away to continue to pollute the water table beneath the atoll. Sea level rise measured at Funafuti, probably caused by global warming, though only about seven cm over the last 13 or so years according to the best data available, makes this phenomenon worse.
