WEBVTT 1 00:00:02.163 --> 00:00:06.983 Dan Distel: The story really began sometime during the late Pleistocene Era. 2 00:00:06.983 --> 00:00:10.143 It was a very different world then. Humans would not arrive 3 00:00:10.143 --> 00:00:14.343 in North America for at least 40,000 years. Giant sloths and 4 00:00:14.343 --> 00:00:18.143 mastodons roamed the continent and vast bald cypress forest 5 00:00:18.143 --> 00:00:21.783 flourished along what would become Alabama's Gulf Coast. 6 00:00:21.783 --> 00:00:25.623 But things were about to change. Climate warmed and sea 7 00:00:25.623 --> 00:00:28.783 level rose submerging the ancient forest beneath the 8 00:00:28.783 --> 00:00:31.583 waves and covering it with a protective layer of sand and 9 00:00:31.583 --> 00:00:36.723 peat which kept the wood in a state of suspended animation. 10 00:00:36.723 --> 00:00:40.123 Hannah Appiah-Madson: The ancient forest remain undisturbed for some 60,000 11 00:00:40.123 --> 00:00:43.203 years until only recently when the violent hurricane waves 12 00:00:43.203 --> 00:00:46.083 scoured the seafloor, uncovering the prehistoric 13 00:00:46.083 --> 00:00:49.803 coastline which now lies 8 miles out to sea and 60 feet 14 00:00:49.803 --> 00:00:53.963 beneath the surface of the Gulf of Mexico. Brian Helmuth: When exposed from 15 00:00:53.963 --> 00:00:56.363 the protective covering of sediment, the ancient trees 16 00:00:56.363 --> 00:00:58.923 were neither petrified nor decayed but instead were 17 00:00:58.923 --> 00:01:02.083 preserved. In many instances, the ancient stubs are still one 18 00:01:02.083 --> 00:01:04.963 of the original positions rooted to the seafloor. The 19 00:01:04.963 --> 00:01:08.323 wood is so fresh and intact that shipworms and other modern 20 00:01:08.323 --> 00:01:11.603 day marine organisms that eat wood can still feed on it and 21 00:01:11.603 --> 00:01:14.603 other organisms that normally burrow in and settle on modern 22 00:01:14.603 --> 00:01:17.523 driftwood can still make these ancient trees their home, 23 00:01:17.523 --> 00:01:19.883 creating one of the most unusual marine environments 24 00:01:19.883 --> 00:01:23.563 ever discovered. Dan Distel: One of the most remarkable aspects of the 25 00:01:23.563 --> 00:01:26.643 Alabama sunken forest is that we know we have only glimpsed 26 00:01:26.643 --> 00:01:30.043 the tiny portion of what's out there. Even now as we dive we 27 00:01:30.043 --> 00:01:32.803 always keep an eye out for new species that have never been 28 00:01:32.803 --> 00:01:35.683 seen before we also know that there's so much more to 29 00:01:35.683 --> 00:01:38.243 discover in the genetic material of these specialist 30 00:01:38.243 --> 00:01:43.023 creatures that rely on underwater wood for their very 31 00:01:43.023 --> 00:01:45.063 survival.
