Body condition of shorebirds upon arrival at their Siberian breeding grounds [PDF]

open access: yes, 2009
Arctic breeding shorebirds carry substantial body stores on their long-distance migrations from their non-breeding grounds. Upon arrival at the breeding area the remains of these stores can be used for egg formation, insurance against poor feeding ...

A Novel Position Estimation Method Based on Displacement Correction in AIS

open access: yesSensors, 2014
A new position estimation method by using the signals from two automatic identification system (AIS) stations is proposed in this paper. The time of arrival (TOA) method is enhanced with the displacement correction, so that the vessel’s position can be ...
