Mary Woo graduated from the University of California, Santa Barbara with a Chemistry degree in 2005, and completed her Ph D in Earth System Science at the University of California, Irvine in 2011.

Any of the radionuclides of carbon, the most common of which are 11C, which has a half-life of 20 minutes, and the beta-emitting 14C, which has a half-life of 5,730 years and is used to date archaeological, geological and hydrogeological material.

It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.

Scientists use this information to learn about the rates at which water circulates through the oceans.

In order to know anything about past climate from corals, we need to know their age.

The radiocarbon (14C) “age” of the coral is the age of the coral, plus the age of the water in which it grew.

Subtracting the former from the latter gives the age of the water in which it grew.

The NBCD 2000 (National Biomass and Carbon data set for the Year 2000) data set provides a high-resolution (30 m) map of year-2000 baseline estimates of basal area-weighted canopy height, above-ground, live, dry biomass, and standing carbon stock for the conterminous United States.One site, run by a fellow named Bill Milstead who is an investor in Triton's efforts, seems to suggest that secret findings are involved and that the results of the study are somehow proprietary ("I cannot divulge the 200 page report...").Thus it seemed time to track down the facts surrounding this report. There is also an Arc GIS shapefile (mapping_zone_shapefile.shp) with the boundaries of all the map zones. Development of the data set used an empirical modeling approach that combined USDA Forest Service Forest Inventory and Analysis (FIA) data with high-resolution In SAR data acquired from the 2000 Shuttle Radar Topography Mission (SRTM) and optical remote sensing data acquired from the Landsat ETM sensor. NACP Aboveground Biomass and Carbon Baseline Data, V. There is a detailed README companion file for each map zone.

  1. Although the currently dating group of young adolescents appear to be a precocious group in terms of risk behaviour relative to the currently non-dating group, teenagers in both groups had experience in the full range of sexual behaviours.
