CTD data from a SeaBird SBE-37 Microcat sensor deployed at a depth of 5 kilometers near Station ALOHA, north of Oahu, Hawaii. The dataset contains rapidly sampled measurements of conductivity, temperature, and pressure from 2011 to 2013, collected by the NOAA National Centers for Environmental Information. Sampling rates changed from 1 minute to 1 second and then to 2 seconds during the deployment.
NOAA/WDS Paleoclimatology archives a tree ring chronology from the Pearl site at Marconi National Seashore, Massachusetts. The dataset provides parameters for reconstructing past climate conditions, covering the period from 148 to -64 calendar years before present. NOAA National Centers for Environmental Information (NCEI) compiled and published this data, with a last recorded update in 2014.
Tree ring data from the Mashpee Pine Barrens in Massachusetts, USA, covering the period from 160 to -64 calendar years before present. The dataset was archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. It was last updated in 2014.
A tree ring chronology from Grinnell Swamp in Massachusetts, United States, covering 201 calendar years from 137 to -64 years before present. The dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in 2014.
Tree ring data from the Westminster Swamp site in Massachusetts, covering the period from 147 to -64 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in 2014.
Swedish mountain forest boundary digitized by the Swedish Forest Agency (Skogsstyrelsen). The boundary is suitable for overview purposes but lacks legal effect. The legal basis is the regulation SKSFS 1991:3.
Over 1,500 fifteen-minute intervals document real-time acoustic whale detections during a dedicated Antarctic voyage. The Australian Antarctic Data Centre compiled this log, where acousticians recorded whale call bearings, group counts, and vessel interactions. Data collection occurred during the 2013 Antarctic Blue Whale Voyage to the Southern Ocean.
2013 acoustic event logs from a Southern Ocean voyage contain sonobuoy-detected whale calls and other sounds, classified by onboard acousticians. The dataset includes processed bearings, frequencies, and estimated receive levels for each event, linked to sonobuoy deployment locations. It was collected by the Australian Antarctic Data Centre during the 2013 Antarctic Blue Whale Voyage.
Reprocessed SEVIRI All-Sky Radiances product contains mean brightness temperatures from all thermal infrared and water vapor channels for 16x16 pixel areas. The product, generated by EUMETSAT using version 1.5.3 software and ECMWF ERA-interim data, includes clear and cloudy sky brightness temperatures, clear sky fraction, and solar zenith angle. Data is BUFR encoded and provided at 3-hourly intervals on every third quarter hour.
Calendar years 160 to -62 before present (BP) are covered by this tree ring chronology from Harvard Forest, Massachusetts. The dataset contains parameters for dendrochronology and paleoclimate reconstruction. It was archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.
NOAA/WDS Paleoclimatology archives a tree ring dataset from the Harvard Forest in Petersham, Massachusetts. The data provides a chronology covering the period from 52 to -58 calendar years before present. This study was contributed by van de Gevel and last updated via NOAA NCEI in 2008.
111 years of tree ring data from the Harvard Forest in Petersham, Massachusetts, covering the period from 53 to -58 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and provides parameters for climate reconstruction. It was last updated in 2008.
Long-term oceanographic observations from two sites in western Massachusetts Bay, LT-A and LT-B, collected by the U.S. Geological Survey. The dataset spans 16 years from December 1989 to February 2006 and includes over 160 mooring deployments across about 90 research cruises. Measurements include current, temperature, salinity, light transmission, pressure, oxygen, fluorescence, and sediment-trapping rate.
Phytoplankton cell counts were collected from May to December 2006 using a moored submersible flow cytometer at the Martha's Vineyard Coastal Observatory in the Northwest Atlantic Ocean. The data were submitted by Dr. Robert J. Olson of the Woods Hole Oceanographic Institution and are recorded as an ASCII (.txt) file.
Phytoplankton cell counts were collected from a moored submersible flow cytometer at the Martha's Vineyard Coastal Observatory in Massachusetts. The data, provided by NOAA NCEI, cover the period from May 2003 to September 2004 and report concentrations for Synechococcus and Eukaryotes in cells per milliliter. Data are stored in yearly, space-separated ASCII text files for 2003 and 2004.
Three permitted artificial reef deployments are represented as vector point data. The dataset, created by SCIOPS, includes supplemental historical and habitat success information accessible via the MORIS Hotlink tool. It was last updated in December 2006.
Long-term oceanographic observations from two sites in western Massachusetts Bay, collected from 1989 to 2006. The dataset includes over 160 separate mooring deployments across about 90 research cruises, measuring parameters like current, temperature, and salinity. The U.S. Geological Survey conducted this study in cooperation with the Massachusetts Water Resources Authority and the U.S. Coast Guard.
Two distinct field studies measured nitrogen loss in selected reaches of the Connecticut River during 2005. A mass-balance study analyzed total nitrogen and streamflow at multiple sites, while a dissolved nitrogen gas study estimated denitrification rates in a 6-mile sub-reach. The data was collected by the USGS to support water-quality modeling and state resource management strategies.
Tornado records provide a chronological listing of tornado events by U.S. state from 1950 onward. The National Weather Service compiled these reports, which include statistics on injuries, fatalities, and damage estimates. Data is coded according to the Pearson Tornado Tape 82-column text format.
Ten days of aerial surveys from July 11 to 29, 2005 recorded the distribution and relative abundance of marine mammals, birds, and large fish over a 1,672 km² study area in the Gulf of Maine. The survey, conducted by SCIOPS, involved six 46 km transects per day, with observations made from a twin-engine aircraft flying at 230 m altitude. Data includes sighting locations, species identifications, and group sizes for upper trophic level predators.
