Popis

This data set provides measurements of soil properties compiled from 39 studies on nutrient dynamics in natural forests and forest-derived land uses (pasture, shifting cultivation and tree plantations) conducted in Amazonia over the period of 1950-2001. The initial literature survey for the data consisted of more than 100 studies conducted during this period.The objectives of this project were to compare soil data from major land uses across Amazonia and identify gaps in present knowledge that offer direction for future research. Five widely cited hypotheses were tested concerning the effects of land-use change on soil properties by analyzing data compiled from 39 studies in multi-factorial ANOVA models:-- effective cation exchange capacity (ECEC), and exchangeable calcium (Ca) concentrations rise and remain elevated following the slash-and-burn conversion of forest to pasture or crop fields soil contents of total carbon (C), nitrogen (N), and inorganic readily (i.e., Bray, Mehlich I or resin) extractable phosphorus (Pi) decline following forest-to-pasture conversion-- soil concentrations of total C, N, and Pi increase in secondary forests with time since abandonment from agricultural activities-- soil nutrient conditions under all tree-dominated land-use systems (natural or not) remain the same-- higher efficiencies of nutrient utilization occur where soil nutrient pools are lower There is one comma-delimited ASCII file (.csv) with this data set and a list of the 39 studies used in this data set provided as a companion file in text format.

Popis

Current meter components data were collected from FIXED PLATFORMS in the NE Pacific (limit-180) from 08 July 1982 to 01 October 1985. Data were collected by the Scripps Institution of Oceanography (SIO). Data were processed by NODC to the NODC standard F015 Current Meter Components format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f015.html. The F015 format contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth and meter characteristics are reported for each station. The data record includes values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north. Data values may be subject to averaging or filtering and are typically reported at 10 - 15 minute time intervals. Water temperature, pressure and conductivity or salinity may also be reported. A text record is available for optional comments.

Popis

The goal of the cruise was to collect data on the abundance, distribution, stock structure, and habitat of cetaceans in the Papah?naumoku?kea Marine National Monument (PMNM) using 7 integrated operations. These operations included visual observations, passive acoustic monitoring, photo-identification, biopsy sampling, satellite tagging, small boat surveys, and oceanography (CTD, Chlorophyll, XBT, and surface samples). A High-frequency Acoustic Recording Package (HARP) was recovered during the cruise.

Popis

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

Popis

Meteorological, oceanographic, wave spectra, and other data were collected from FIXED PLATFORMS in the North Atlantic Ocean and other locations. Data were collected by the National Data Buoy Center (NDBC) from 01 January 1991 to 31 January 1991. Data were processed by NODC to the standard NODC F291-Meteorology, Oceanography, and Wave Spectra from Buoys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f291.html. Links to digital data are not available at this time. An analog file is available from NODC user services. The F291 format is used to report meteorological, oceanographic, and wave spectra data from NDBC moored buoys and fixed land stations. The format contains thirteen data record types to: 1) Identify the buoy position and other descriptive information; 2) report the meteorological measurements; 3) report wave energy spectra and wave direction; 4) report subsurface physical, biological and chemical oceanographic measurements; and 5) report detailed information on continuously measured wind speed and direction. Each record is 120 characters in length, sorted by station and record type. Record type is omitted where data defined in that type and not measured. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (columns 4-9). The file identifier, assigned by the originator, is a unique originator id for each data submission. After submission, the NODC reassigns to this field a unique and NODC identifier for internal use.

Popis

Data from Coral Reef Ecosystem Division (CRED), NOAA Pacific Islands Fisheries Science Center (PIFSC) Subsurface Temperature Recorders (STR) provide a time series of water temperature at coral reef sites. Data is typically collected at 1800 second intervals for a duration of 2 years using a SBE39 Temperature Recorder (Sea-Bird Electronics, Inc., www.seabird.com). When a STR is recovered, a new one is typically deployed in the same place. Time series data combining multiple deployments from a given site may also be available. Please contact CRED with any questions. For program information see the web site http://www.pifsc.noaa.gov/cred/oceanography.php

Popis

This data set reports soil carbon dioxide (CO2) and nitrous oxide (N2O) concentrations and soil volumetric water content (VWC) from a rainfall exclusion experiment that was conducted at the km 67 Seca Floresta site, Tapajos National Forest, Brazil. Samples were collected every two to three months. The purpose was to observe the potential effects of severe water stress on a humid Amazonian forest (Nepstad 2002).Data provided are from December 9, 1999, and April 2, 2000-June 14, 2002. There is one comma-delimited data file with this data set.
