Bost, C.A., Thiebot, J.B., Pinaud, D., Cherel, Y., Trathan, P.N. (2009). Where do penguins go during the inter-breeding period? Using geolocation to track their winter dispersion. Biol. Lett., 5, 473–476.
Abstract: Although penguins are key marine predators from the Southern Ocean, their migratory behavior during the inter-nesting period remains essentially unknown. Here, we report for the first time the winter foraging movements and feeding habits of a penguin species by using geolocation sensors fitted on penguins with a new attachment method. We focused on the macaroni penguin Eudyptes chrysolophus at Kerguelen, the single largest consumer of marine prey among all seabirds. Overall, macaroni penguins performed very long winter trips, remaining at sea during ~6 months within the limits of the Southern Ocean. They departed from Kerguelen in an eastward direction and distributed widely, over >3.106 km². The penguins spent most of their time in a previously unrecognized foraging area, i.e. a narrow latitudinal band (47-49°S) within the central Indian Ocean (70°-110°E), corresponding oceanographically to the Polar Frontal Zone. There, their blood isotopic niche indicated that macaroni penguins preyed mainly upon crustaceans, but not on Antarctic krill Euphausia superba that does not occur at these northern latitudes. Such winter information is a crucial step for a better integrative approach for the conservation of this species whose world population is known to be declining.

Abstract: The confirmed discovery of an adult female of an as yet undescribed species of the genus Nesiotinus (Phthiraptera, Ischnocera, Philopteridae sensu lato) on a Kerguelen Diving-petrel appears to provide the first certain parasitophyletic evidence for a phylogenetic relationship between penguins (Sphenisciformes) and tubenoses (Procellariiformes). An over-view of the hospital distribution of chewing lice genera parasitising penguins and tubenoses is given.

Dufumier H. (1996). On the limits of moment tensor inversions of teleseismic body wave spectra. Pure and applied geophysics, 147(3), 467–482.
Abstract: The limits of linear moment-tensor inversions from long-period teleseismic body waves are analysed in detail, using inverse methods. We focus our attention on single-station and few-stations methods. Information on the feasibility of full or deviatoric moment-tensor determinations prior to inversion are deduced from the system conditioning. The resolution and correlation of the momenttensor components are analysed using the resolution matrix. Conclusions on the importance and independence of the data are drawn from the information matrix. The single--station case and its implications are discussed in greater detail, as well as possible constraints on the inversion.

Abstract: To distinguish between Fe(II) and Fe(III) species in atmospheric water samples, we have adapted an analytical procedure based on the formation of a specific complex between Fe(II) and ferrozine (FZ) on a chromatographic column. After elution of Fe(III), the Fe(II) complex is recovered with water-methanol (4:1). The possibility of trace iron measurements in this complex medium by graphite-furnace atomic-absorption spectrometry has been investigated. A simplex optimization routine was required to complete the development of the analytical method.
