    08:54 Modern tidal-flat drone surveyBefore the school visit, the team planned a drone survey of the modern tidal flat while GPS/ruler measurements recorded tidal-flat elevation and water depth.

    Raw transcript

    Before school this morning we're going to do a quick survey with the drone of the modern tidal flat. The GPS and ruler team is going to walk through the water measuring the tidal flat elevation and noting the water depth on the GPS comment. I will fly the drone just in sort of a pan view over the tidal flat pretty high resolution.

    A bunch of photographs of the reef right up against the sea. We'll now walk on transect back towards the second high cliff. This reef looks a lot like what we've seen. All framework. Pedial groups preserved with encrusters inside and in the bottom of them. Yep, pretty standard.

    14:24 HS115: High-Cliff Shoreward Transect weathering transition into treesHS115 weathering transition into trees: Weathering changes into the trees may reflect vegetation effects, landward reef position, early cementation, or bioencruster abundance.

    Raw transcript

    The weathering chain is a little bit as we get into the trees. It's unclear if that's just because there are trees here or if we're moving further back on the reef to a place where there's more maybe early cementation or bio encrusters.

    14:25 HS115: High-Cliff Shoreward Transect cleared flat with in-situ coralsHS115 cleared flat with in-situ corals: Cleared flat contains pits, sand, moved boulders, and still-obvious in-situ large corals, making it a likely tidal-flat surface associated with the first high cliff/MIS 5e reef.

    Raw transcript

    Out on the flat now it's clearly been at least partially cleared. There are pits where maybe a backhoe has dug, a lot of sand, some large boulders that have been moved, but underfoot it's clear there's still large corals in situ. A few photographs sort of verifying that. So very likely this is the tidal flat surface associated with the first height cliff in mass 5e.

    Raw transcript

    A perched boulder on the first high cliff right on top of the healthy coral reef may be a 5e analog of the photograph I took a few minutes ago of the 5e boulders falling into the Holocene tidal flat. Maybe this is the stage 9 or 11 cliff, the last rim then of it as it erodes back.

    Raw transcript

    At the top of the flat, when you get back into the trees, there are little sort of meter scale outcroppings of carbonate. It's very pink red, modeled, full of holes and bugs. Again, hard to tell how much of this is. The pendant is trees versus primary. The rocks themselves, they have bits of coral, they have a lot of texture, suggestive of recrystallization, maybe back reefing encrusters, but maybe it's happening because of the plants and the roots. We'll continue on to the next outcrop on the other side of the trees next.

    Two photographs showing sort of the lay of the land there are gentle slope up to the cliff with some mounds in the front that said a little bit higher trees separate them and maybe a slightly higher feature along the wall and the cliff itself I'm not sure is the highest cliff I have to keep going I think there's a close nearby one that's even higher.

    Raw transcript

    There's a distinct sort of blue to black color change here right on the front of the cliff. This is the feature that far away I sort of suggested that maybe there was a third thing along the cliff that looked like a break. I think what I was seeing was the color change. This is where there's a little bit more smoothly than the upper rocks which are more carstered.

    Raw transcript

    Speculating that the fallen blocks have actually been part of the top of a sea cave or the cliff during stage 9. Sea level came up, notched into the wall here. Corals grew in front of it and then eventually these pieces just fell down. The slope has kind of also relaxed a bit and all the corals are sort of down in this field without very many trees.

    Raw transcript

    Just take a bunch of photographs on a transect from the car up to the stage 11 cliff or the second high cliff. We stopped the car because there were a bunch of looks like almost like Casarina but like a pine-like tree. It looked like a grove that was really tall. We were curious if that was topography or just trees and we walked in and found that it actually was a very high reef. Large in situ corals, of course the weathering kind of sucks underneath the trees but feels quite a bit higher than what we just surveyed. Likely the stage 9 reef, the photos at the end show the backside where we kind of step out onto the second cliff and the corals suddenly stop right at the base of this cliff.
