Scott Base was built in the summer of 1956/7 at Pram Point, Ross Island, initially to provide accommodation for the Ross Sea Support Party of the Commonwealth Transantarctic Expedition (NZ TAE) and for the New Zealand International Geophysical Year Antarctic Expedition (NZ IGY). It has generally been accepted that it was built primarily by and for the Ross Sea Support Party. This is reflected in naming one of the last, conserved, original huts (Hut A) after the NZ TAE and also in ignoring the existence of the other original huts (Hut G and H) still in use. The contribution of the NZ IGY programme to Scott Base (SB) has received little recognition. Furthermore, SB provided a presence in the Ross Dependency to support the New Zealand claimant position. The specifications for the base buildings were developed by a joint committee from both expeditions with final design by the Ministry of Works of the New Zealand Government. The base was constructed and largely paid for by the New Zealand Government. This note briefly reviews what occurred during the conception, design, construction and payment for the base.

New determinations of ocean tides are extracted from high-rate Global Positioning System (GPS) solutions at nine stations sitting on the Ross Ice Shelf. Five are multi-year time series. Three older time series are only 2–3 weeks long. These are not ideal, but they are still useful because they provide the only in situ tide observations in that sector of the ice shelf. The long tide-gauge observations from Scott Base and Cape Roberts are also reanalysed. They allow determination of some previously neglected tidal phenomena in this region, such as third-degree tides, and they provide context for analysis of the shorter datasets. The semidiurnal tides are small at all sites, yet M2 undergoes a clear seasonal cycle, which was first noted by Sir George Darwin while studying measurements from the Discovery expedition. Darwin saw a much larger modulation than we observe, and we consider possible explanations - instrumental or climatic - for this difference.
