Antarctic Expedition Index: Royal Society Collection
In September 1929, at Mawson's request, Morton Henry Moyes (1886-1981) was seconded to the British, Australian and New Zealand Antarctic Research Expedition, which was to assert British territorial claims in Antarctica by means of two voyages in the auxiliary barque, Discovery. Moyes joined the scientific staff as survey officer, spending long hours operating a defective echo-sounder, taking sights and drawing charts, helping with tow-nets, and assisting Mawson in executive matters. This note book notes details of stores and packing
in holds, including such items as clothing, balaclavas,
oil skins, snow-shoes, boots, equipment, instruments, etc.
and notes of use and issues of items.

An Efficient Automated Validation Procedure for Exoplanet Transit Candidates
Surveys searching for transiting exoplanets have found many more candidates
than they have been able to confirm as true planets. This situation is
especially acute with the Kepler survey, which has found over 2300 candidates
but has confirmed only 77 planets to date. I present here a general procedure
that can quickly be applied to any planet candidate to calculate its false
positive probability. This procedure takes into account the period, depth,
duration, and shape of the signal; the colors of the target star; arbitrary
spectroscopic or imaging follow-up observations; and informed assumptions about
the populations and distributions of field stars and multiple-star properties.
I also introduce the concept of the "specific occurrence rate," which allows
for the calculation of the FPP without relying on an assumed planet radius
function. Applying these methods to a sample of known Kepler planets, I
demonstrate that many signals can be validated with very limited follow-up
observations: in most cases with only a spectrum and an AO image. Additionally,
I demonstrate that this procedure can reliably identify false positive signals.
Because of the computational efficiency of this analysis, it is feasible to
apply it to all Kepler planet candidates in the near future, and it will
streamline the follow-up efforts for Kepler and other current and future
transit surveys.Comment: accepted to Ap
