marine heatwaves blob stacks up
2016/4/13
Unusually warm oceans can have widespread effects on marine ecosystems. Warm patches off the Pacific Northwest from 2013 to 2015, and a couple of years earlier in the Atlantic Ocean, affected everythi...
A Hybrid Variational Front Tracking-Level Set Mesh Generator For Problems Exhibiting Large Deformations and Topological Changes
Front Tracking Arbitrary-Lagrangian-Eulerian Mesh Method
2015/12/11
We present a method for generating 2-D unstructured triangular meshes that undergo large deformations and
topological changes in an automatic way. We employ a method for detecting when topological ch...
MEASURING COMPLETE GROUND-TRUTH DATA AND ERROR ESTIMATES FOR REAL VIDEO SEQUENCES, FOR PERFORMANCE EVALUATION OF TRACKING, CAMERA POSE AND MOTION ESTIMATION ALGORITHMS
Vision robotics tracking navigation registration
2015/8/14
Fundamental tasks in computer vision include determining the position, orientation and trajectory of a moving camera relative to an
observed object or scene. Many such visual tracking algorithms hav...
When it comes to body clocks, pandas are the rugged individualists of the forest.The research team led by scientists at Michigan State University (MSU) that has spent years getting unprecedented peeks...
Advances in Conservation Oceanography: New Tagging and Tracking Technologies and Their Potential for Transforming the Science Underlying Fisheries Management
Conservation Oceanography New Tagging
2015/7/3
Overexploitation of living resources and climate change are among the most obvious global-scale impacts of human society on marine ecosystems. In an age of such large-scale anthropogenic impacts, mari...
Animals wearing new tagging and tracking devices give a real-time look at their behavior and at the environmental health of the planet, say research associates at the Smithsonian Tropical Research Ins...

The monk parakeets that have invaded Europe and North America over the last 40-50 years fortifying their massive communal nests atop utility poles in many urban areas appear to have originated from th...
Tracking the Evolution of Mid Cenozoic Silicic Magma Systems in the Southern Chocolate Mountains Region, California Using Zircon Geochemistry and Quartz and Zircon Geothermometry
Chocolate Mountains zircon quartz geothermometer geochemistry
2015/1/16
During the mid Cenozoic, the Chocolate Mountains region of southeastern California experienced crustal extension slightly before, during, and after the main pulse of magmatism. This combined with mid-...
CycloTRACK (v1.0) – tracking winter extratropical cyclones based on relative vorticity: sensitivity to data filtering and other relevant parameters
winter extratropical cyclones relative vorticity sensitivity to data filtering other relevant parameters
2014/12/19
In this study we present a new cyclone identification and tracking algorithm, cycloTRACK. The algorithm describes an iterative process. At each time step it identifies all potential cyclone centers, d...
