We examined the role played by temperature in the duration of incubation and sex ratio of green turtle hatchlings at Ascension Island, one of the most important green turtle rookeries in the Atlantic. Temperature at control sites at nest depth and in 39 green turtle nests was measured using small temperature recording devices. The sex ratio of hatchlings was ascertained in a sub-sample of monit...

The 352 MHz Westerbork In the Southern Hemisphere (WISH) survey is the southern extension of the WENSS, covering 1.60 sr between −9 < δ < −26 to a limiting flux density of ∼18 mJy (5σ). Due to the very low elevation of the observations, the survey has a much lower resolution in declination than in right ascension (54 × 54cosecδ). A correlation with the 1.4 GHz NVSS shows that the positional acc...

The underground muon flux produced by primary cosmic rays with a median rigidity of 1.5 x 10 V has been monitored to search for periodic and transient rate variations. The detector has operated at an average rate of 4.47 Hz for most of the 1.2 yr interval starting 1978 Jan 1. A peak with relative amplitude (3.8 ± 0.9) x10 -4 is observed in the Fourier transform of data at the sidereal 0.9 frequ...
