Diving Deeper into IM2GPS

Management of tuberculosis in India: time for a deeper dive into quality.

Maximum Dive Depths of Eight New Zealand Procellariiform including Pterodroma Species

Lightweight capillary tube depth gauges were attached to breeding at New Zealand colonies during the period 1998-2008. This paper presents the first information on the diving ability of Pterodroma Grey-faced Petrels, Pterodroma macroptera gouldi, recorded maximum dives down to 23 m. Males (6.3 ± 6.3 m SD) dived deeper on average than females (3.6 2.5 m) during the incubation period but not sign...

Large-Scale Image Geolocalization

In this chapter, we explore the task of global image geolocalization— estimating where on the Earth a photograph was captured. We examine variants of the “im2gps” algorithm using millions of “geotagged” Internet photographs as training data. We first discuss a simple to understand nearest-neighbor baseline. Next, we introduce a lazy-learning approach with more sophisticated features that double...

Diel Oscillations in Whale Shark Vertical Movements Associated with Meso- and Bathypelagic Diving

—A female whale shark Rhincodon typus satellite tagged off the coast of Mozambique and moving to the east coast of Madagascar where the tag popped off after 87 d showed increased mesoand bathypelagic diving while crossing the bathymetrically nonconstraining southern part of the Mozambique Channel. After three weeks with daily maximum diving depths in the epipelagic zone at the beginning of the ...

Flipper stroke rate and venous oxygen levels in free-ranging California sea lions.

The depletion rate of the blood oxygen store, development of hypoxemia and dive capacity are dependent on the distribution and rate of blood oxygen delivery to tissues while diving. Although blood oxygen extraction by working muscle would increase the blood oxygen depletion rate in a swimming animal, there is little information on the relationship between muscle workload and blood oxygen deplet...
