NPR/NGS RADIO EXPEDITIONS Show: Palmyra Log of DAT #: 3 Engineer: Chuck Thompson Date: May 2000 ng = not good ok= okay g = good vg = very good AC: ALEX CHADWICK CT: CHUCK THOMPSON 0:40 CT: 11 :20 AM, overcast, Palmyra, pair of DP A 40160 omnis, rycote housing 1:44-3:55 AMB-walking, birds in bkgnd, sometimes no walking (birds only) 4:33-6:56 AMB-wind or rain, birds in bkgnd CT: terns, and palm leaves blowing after rain shower 7:17-9:55 AMB: palm trees, wind, birds, another location G CT: another palm grove, high wind 10:22-11:30 AMB: same deal 11 :44 CT: these are MS mics, MKH 40/30¬AC: on previous recording, those were white terns flying at about 20 ft above us, the sound they make is quite distinctive ... Jim could you imitate that sound? JIM: (IMITATES SOUND) and there were four of them in their courtship behavior. AC: the terns are perfectly white and they have a black beak like a pair of needlenose pliers. Very sharp, like a supersonic jet nose. CT: a walk on the trail, following AC and Jim 12:56-14:51 AMB walking on the trail, some bird noise 14:52 AC: hello, camp visitors ... 14:53-15:36 AMB: walking, a little squishy sounding 15:46 JIM MARAGOS (JM): I'm JM, coral reef biologist for the F & W service. AC: would you describe this place? JM: we're standing on the north side of cooper island and we're looking out to sea. In front of us is a reef flat about 'l4 mile wide, it's v glassy. Off to our right we've got some palm trees hanging in the water, straight ahead of us we've got some low surf, 2-3 ft high, breaking on the outer edge of the reef maybe 113 mile in front of us. Off to the left we have the curvature of the beach, few palm trees in the water, some terns flying in the sky and making some noise. AC: in terms of the structure of Palmyra, what's going on here? What is all this, the physiology of the island. JM: the main situation going on here right now is that this shoreline is eroding and has been eroding for probably the last half century. The main reason is the navy put in causeways to the east and west of us, and those ca8useways block the flow of water across the reefs and into the lagoon. And so the water has had to pile up and move along the coast at a greater rate, and as it does it's more erosive and its taking sand with it and causing the beach to erode and the reefs to be covered with sediment. 17:21 AC: but in terms of the reef flat and the reef crest out there, when you look at this what do you see about how atolls work. JM: the reef flat represents an equilibrium depth in which corals and coral (?) and other reef building ) organisms, they grow up, they're marine in nature so they cant grow up any higher than mean low water. So once they reach mean low water they can only grown out, away from the atoll. So what we have here is a reef flat that has grown probably over the last 10tousand years, and it keeps extending seaward if it s growing. And in all cases in the pacific and the central pacific, all the coral reefs are growing fairly vigorously. and so what's happening then is its growing outward inch by inch over millennia, and on the outer edge of the reef is where the battle is being fought, between wave action crashing on the reef and the reef trying to grow in the face of this wave action.
