Life Studies Controversial
Life Studies of lifeforms in the hypersaline (and/or brine) water of Don Juan Pond have been controversial.
Anyone know how large it is? Deuar 21:38, 27 June 2007 (UTC)
- Based on this picture (from here) I'd estimate about 100 feet across. Note the person on the right side of the photo. 220.127.116.11 (talk) 21:23, 16 February 2008 (UTC)
I've seen figures of cirka 300 × 100 m (984 × 328 ft) with a depth of 10 cm (4 in) a couple of times (Yamagata et al. 1967). This puts the area at around 0.03 km², though the pond's size varies. --Anshelm '77 (talk) 01:20, 25 February 2008 (UTC)
- For the record, the bibliographic record of Yamagata et al. 1967: Yamagata, N., T. Torii, S. Murata: Report of the Japanese summer parties in Dry Valleys, Victoria Land, 1963-65; V - Chemical composition of lake waters. Antarctic Record 29: 53-75. --Ratzer (talk) 07:21, 23 October 2008 (UTC)
The comparison of life on Don Juan Pond brine with life on Mars' brine (recurring slope lineae) is not substantiated so I deleted the text and refs. The NY Times quotes Chris McKay saying nothing grows on the water of Don Juan Pond. Other than that, no cited paper compares the 2 brines, which by the way are indeed different: Mars' brine is perchlorate salts, while the Don Juan Pond is CaCl2 and NaCl. In addition to that, there is the variable of atmospheric pressure. Cheers, BatteryIncluded (talk) 14:31, 30 September 2015 (UTC)
- BTW, comparing their antifreeze properties has been done extensively in the literature, and would be useful here. BatteryIncluded (talk) 14:46, 30 September 2015 (UTC)
