The objectives of The 6th Chinese National Arctic Scientific Research Expedition were to improve understanding of basic environmental information of marine hydrology in high latitude areas. The China Arctic Expedition of 2014 (Chinare 2014) campaign was designed to provide basic information for global climate change research. The main work was undertaken through sectional observations of the above mentioned sea areas. During the 6th Chinese National Arctic Research Expedition, about 14 days (2014.7.22—2014.8.4) had been taken to investigate the marine physical, chemical oceanography and biological ecology, as well as marine geology. Different parameters had been observed, including 53 CTD sites, 53 LADCP sites, 12 Chlorophyll sites, 19 Zooplankton sites and 22 Nutrients sites. Besides, 16 sedimentary cores or surface sediments had been collected. These data are submitted as part of the World Data Service for Oceanography, Marine Research data U2014-022. Data are in text, XLS, and binary formats. The objectives of The 6th Chinese National Arctic Scientific Research Expedition were to improve understanding of basic environmental information of marine hydrology in summer 2014 in areas of the Bering Sea, Chukchi Sea, Chukchi Sea Rise and Canadian Basin, and to provide basic information for global climate change research.

NOAA National Centers for Environmental Information custodian Acoustic Doppler Velocimeter (ADV) Acoustic Doppler Velocimeter (ADV) High-resolution acoustic instruments to study rapid 3D velocity fluctuations ADVs have three or more focused beams to measure with high sampling rates in a small point. They work by sending out a short acoustic pulse from the transmit element. When the pulse travels through the focus point for the receiver beams, the echo is recorded in each of the acoustic receiver elements. The echo is then processed to find the Doppler shift, the scaling is adjusted with the measured speed of sound in the liquid (hence the temperature measurement), and the velocity vector is recorded or transmitted to a PC at a rapid rate. http://www.nortek-as.com/en/products/velocimeters bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle.
