07:58 Tarapaku landing framework and notchTarapaku landing has an accessible steep path/canoe-ramp area, massive Porites-rich framework, and a 1-3 m coastal notch to compare with published Atiu bench/notch features.
Raw transcript

Drove a road from town to the northeast, right at the end, stopped at the landing. Very steep path down to the water, but it's accessible. Massive framework coral reef with huge parais. I'll take a photo here in just a second. And additionally, along the coastline, there's a notch, sort of three, maybe one to three meters high, that maybe the early Holocene high stand, we've seen sort of the same elevation in quite a few places. The landing is called Terra Paku.

08:03 Tarapaku Porites framework photosTarapaku Porites framework photos: a massive Porites colony with borings, encrusters, branching corals, and a nearby elevated notch.
Raw transcript

Two photographs. The first is of the massive Parites colony. The top of it is colonized by encrusters, full of borings. They create these sort of crinkly laminations and sort of go around the entire coral colony. And then above you have sort of platey thick encrusters and branching coral, smaller stony corals. But up to the right there's another large colony. This just feels like a massive framework reef with some really large and happy corals. Second photograph with Billy for scale shows the notch that I mentioned that maybe early Holocene. It could be an erosional feature. You can see it down the coast in a few places and I'll try and capture it with the drone so we can really test whether that elevation matches the tables that we've seen in other places. This is a good site to collect maybe a GPS point along the modern notch. If the GPS will be able to sort of see the atlas configuration from this cliff face.

08:19 Tarapaku cemented reef-flat surfaceTarapaku reef-flat sediment is hard cemented material with shell and grain debris around corals, raising a comparison to rapid cementation at the HS104 harbor surface.
Raw transcript

Tilly asked a great question about the paleo environment and we looked at the ground we're standing on which is actually full of grains and shells that broke out up into coral and sand but it's hard as a rock so it really seems like this surface probably just fills up to the lowest water level and stays here and the corals are all short-lived, they die, they roll around, they get cemented pretty fast and reflected on whether the environment we're looking at in the reef yesterday at the harbor whether or not that surface could have accumulated in a much the same way like at any point in time it was all hard because cementation happened so fast.

08:27 Tarapaku microatoll sea-level targetFlat microatolls on the reef flat were noted as a promising sea-level indicator if the same short, horizontal growth form can be found in the upper unit.
Raw transcript

The flat micro-atolls in this reef flat, actually an excellent sea level indicator. And hypothetically we would see them in our crop just like we had at the harbor. At the harbor we never saw that growth form or that context of the corals. But we should keep our eye out in that kind of environment where you have high coral diversity, sand. And if suddenly we see a bunch of corals growing horizontally and they're not very tall, then we might actually be at sea level. So maybe we don't need a beach in Phanestra to get a precise sea level indicator here in the Cook Islands as I was sort of pessimistically thinking yesterday. If we can find the right morphology of coral in the upper unit, then we might actually also be exactly what we need.

09:23 HS106 lower/upper reef contrastHS106 lower exposure has large intact meter-scale corals; higher outcrop resembles HS104 with smaller corals, encrusters, and reef-framework material, with no clear microatoll-style flat found in the jumble.
Raw transcript

HS106 summary. Lower down, large intact, very large meter scale, corals. Many photographs early on from here from the site. In the higher part it's a lot like the harbor. We have smaller corals, thrusters, all kinds of sort of reef framework material, but nothing, no really large colony, so we see a lot of our still sub-meter scale corals. We poked around in the very job trying to find evidence of any kind of flat, micro-atoll style growth patterns, but haven't seen that.

Raw transcript

A quick stop in the woods to see a boulder that we could see from the road walked out to the cliffs and sort of at a place where the shelf is basically even with the cliffs and you can see these nice sort of constructional terraces where the waves crash much like what I've seen in Barbados and a few other places with highway energy right up against the tidal notch. I took a photo deep water right off to the north a very flat top to the unit and a wide sort of open plain flat shelf so it's just this narrow little bit here that doesn't have much of a shelf.

16:56 HS107 coral-clam reef tableHS107 has articulated tridacnid clams, abundant mollusks, diverse in situ corals, ocean-oriented gullies, and possible primary constructional relief versus modern cemented rubble.
Raw transcript

After walking HS107, just some observations, lots of articulated tridactinid giant clams. Other bivalves and gastropods are certainly abundant. Tons of coral, really all the species and types we've seen so far, even different forms, are all in situ, often sort of meter scale clumps of stony corals separated by these little canyons or valleys that run towards the ocean. There are corals that are sort of lined up with that same orientation. So something Billy called pseudo-palmata because of how it grows seems to be lined up in the same orientation as these little gullies. At the gullies, there's a lot of breccia and sort of corals that seem to be growing into the gullies which suggest that perhaps they're primary, so primary topography on this old surface. Of course they could be modern and just falling in place and cementing. It's hard to distinguish the two. The way that this outcrop weather is really spectacular. You can really see all of the features of the corals. It's pretty tough on the boots though.
