abstract: These datasets were collected during the research vessel Araon cruise 12, 2nd Leg (ARA12B) in summer of 2021 and submitted by Kyoung-Ho Cho from the Korea Polar Research Institute (KOPRI), who was the chief scientist of the ARA12B cruise. There are several categories: physical, chemical, biological, meteorological, and underway. Physical dataset includes CTD and Lowered ADCP measurements. Chemical dataset includes nutrients, DIC, and total alkalinity (TA). Biological dataset includes Chl-a (concentration and size fraction), pigment, zooplankton abundance, microzooplankton abundance, bacterial abundance, and photochemical efficiency of phytoplankton. Meteorological dataset includes air temperature, relative humidity, air pressure, wind, shortwave/longwave radiations, and radiosonde observations. Underway data include pCO2, black carbon concentration, and inherent optical properties. Meteo and underway were collected quasi-continuously during the entire cruise, cover larger area, and have longer time span. This cruise is U.S. State Department MSR U2021-010 as part of the World Data Service for Oceanography. Data are in CSV and text formats.
purpose: This dataset is available to the public for a wide variety of uses including scientific research and analysis.

instrument: (MI_Instrument)
identifier: (MD_Identifier)
code: ADCP
type: ADCP
description: Acoustic Doppler Current Profiler The Acoustic Doppler Current Profiler (ADCP) measures currents beneath a ship while underway. Sound signals sent from the moving ship bounce back to receivers aboard the ship. This provides a profile of water movement relative to the ship-precise modern navigation, allowing the ship's motion to be subtracted from the data. These devices are also used on moorings and profilers and, along with acoustic backscattering, measure animal biomass. Particles in the path of the sound waves, mostly plankton, reflect a small part of the sound energy back toward receivers, allowing researchers to make remote estimates of the sizes and numbers of animals present in the water column. Before the 1970's, the most technologically advanced instrument used to measure water velocity was known as a Doppler speed log. This evolved into the first commercial ADCP, produced in the mid-1970's, which used averaging. Later in the 1970's, the first vessel-mounted ADCP was developed to measure water velocity more accurately and to allow measurement in range cells over a depth profile. As instruments evolved, so did new techniques in Doppler signal processing. Initially, Doppler speed logs used simple analog signal processing methods, which are still used in some commercial speed logs today. However, the first ADCPs incorporated analog-to-digital signal conversion over a narrow communication bandwidth. Around 1990, this technique was developed into broadband signal processing. Since then, broadband ADCPs have been able to generate very accurate, real-time velocity measurements.

description: Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm)
