Last night we watched the documentary on James Cameron's expedition to the bottom of Challenger Deep of the Mariana Trench. There were critters and, while the camera gazed lovingly at them for moments, the narrative quickly skipped over any details. The focus was on the expedition itself, which was interesting from an engineering project management point of view and from a human interest point of view. Project management: really? You schedule the ship to arrive before the submersible is ready? Oh to have the edited footage that the scientists analyzed for critters and just gaze at the depths for an hour or so!

So.

Does the website from National Geographic link to scientific papers about the trip? No. Are there papers? Yes. I read the paper about the community patterns last night. I found the microbial mats paper this morning. There were also big -- giant! -- amoeba called xenophyophores - i hope to find a paper on them.

I delight in Google Image search as an assist when reading that scientists prior to the trip "identified several distinctive features that characterize hadal communities including a) dominance of certain groups like the actinians, polychaetes, isopods, amphipods, echiurids, and holothurians, b) lower representation of non-holothurian echinoderms, c) insignificance or lack of fish and decapod crustaceans and d) mass-occurrence of holothurians at maximal trench depths."

I'm realizing that these days i read fewer books but delight in reading various science papers as topics catch my interest. Instead of book lists, i now use Zotero to collect the citations for both the professional documents and my diversionary reading. A browser plug in, Lazy Scholar, helps me find full text on occasion, although this morning i note that it can't find the full text of the paper presented in full on the Science Direct website. I will blame Elsevier (which always produces a satisfying sense of self righteousness).

Off i go to day two of the internet identity workshop, hoping to return this evening not feeling exhausted by the pressure of so many people talking and presenting myself as a competent being. I am tired of feeling so tired, which does seem a depression symptom.
