Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates...
The NASA Ames Mars General Circulation Model is used to interpret selected results from the Mars Pathfinder atmospheric structure instrument/meteorology (ASI/MET) experiment. The present version of the model has an improved soil thermal model, a new boundary layer scheme, and a correction for non-local thermodynamic equilibrium effects at solar wavelengths....
An instrument on the Pathfinder lander has been designed to measure the structure of Mars’ atmosphere during spacecraft entry and descent from ~150 km altitude to the surface, and to measure meteorological parameters after landing for the landed duration of the mission. This is specified to be nominally 30 Mars...
Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated
a small rover about l00 m clockwise around the lander, and collected data from three science
instruments and ten technology experiments. The mission operated for three months and returned
2.3 Gbits of data, including over 16,500...

Nitrate concentrations, chlorophyll a (Chl a) fluorescence, radiance, salinity, and
temperature were measured on the Hawaii Air-Sea Logging Experiment, A Long-Term
Oligotrophic Habitat Assessment (HALE ALOHA) mooring located near the Hawaii
Ocean Time-Series (HOT) Program’s Station ALOHA (22°45’N; 158°W). Nitrate
concentrations were determined with OsmoAnalyzers deployed at depths of 120...
