Declining Body Condition of Territorial Male Australian Fur Seals: Correlations With Environmental Variables

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT The Australian fur seal ( Arctocephalus pusillus doriferus , AUFS) population, currently less than 47% of its pre‐harvest size, represents the largest resident marine predator biomass in south‐eastern Australia. This region, characterized by low marine productivity and rapid warming, is home to Kanowna Island, the third‐largest AUFS colony ...

Poisson filtering of laser ranging data [PDF]

, 1993
The filtering of data in a high noise, low signal strength environment is a situation encountered routinely in lunar laser ranging (LLR) and, to a lesser extent, in artificial satellite laser ranging (SLR).

18.6-yr tidal variations in J2 observed from 48-yr satellite laser ranging (SLR)

Geophysical Journal International
SUMMARY Analysis of the 48-yr of satellite laser ranging data of multiple satellites shows that long-term variations in the Earth's dynamical oblateness represented by the second-degree zonal harmonic J2 is best characterized by the superposition of a quadratic trend, 10.5- and 18.6-yr variations.
