Coastal oceans are most likely to be impacted by anthropogenic activities because they are typically shallow and have more restricted water circulation than the open ocean. Kaneohe Bay served as a test site to gain insight into aspects of the carbon cycle. It is a semi-enclosed bay located on the eastern side of the island of Oahu, Hawaii and is the largest sheltered body of water in the islands. Thirteen profile stations were established and nine cruises were conducted during 2004-2009 on the R/V Kaholo. Cruises took place at various times of the year so that changes in carbon system parameters could be observed under varying conditions. Each cruise transect was 16 km long. This dataset includes temperature, salinity, oxygen, pH, and other ancillary parameters.

The ALOHA Cabled Observatory (ACO) is a system of hardware and software that extends electric power and the Internet offshore, supporting sustained real-time observations in the deep ocean. The ACO is connected to Oahu, Hawaii by the HAW-4 telecommunications cable transferred to the project by AT&T in 2007. On June 6th, 2011, the ACO was deployed on the ocean bottom (depth ~ 5 kilometers - 3 miles) near Station ALOHA, 100 kilometers (60 nautical miles) north of Oahu, Hawaii. Station ALOHA is the site of the long-term Hawaii Ocean Time-series (HOT) open ocean measurement program, visited by research vessels 10-12 times each year since October 1988. There are five modules that are connected together on the seafloor. The Junction Box is connected to the HAW-4 cable and to the Observatory module. Together, they supply 1200 watts of power and 100 Megabits per second of Ethernet communications to sensor systems on these two modules, and to the other three modules. The other modules are the Camera tripod, the AMM bottom node, and the TAAM mooring. Sensors provide live video of the ocean bottom around the ACO, sound from local and distant sources, currents, pressure, temperature, and salinity. This data set contains the rapidly sampled CTD data from a SeaBird SBE-37 Microcat during 2011-2013. The initial sampling rate was 1 minute, and it was changed to 1 second on June 27th, 2011, and to 2 seconds on December 28th, 2011. Salinities were calculated using the UNESCO routines. Currents from ADCP are available separately. The project is ongoing with data from 2014 to become available.

This dataset includes chemical, discrete sample, physical and profile data collected from Hakuho Maru in the North Pacific Ocean from 1993-05-13 to 1993-05-30 and retrieved during cruise KH93-2 Leg 1 and PACIFICA_49HH19930513. These data include DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, Potential temperature (theta), SALINITY and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography (MIO) and Keisuke Taira of ORI as part of the PACIFICA_49HH19930513 dataset. PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for the data synthesis of ocean interior carbon and its related parameters in the Pacific Ocean. The North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC) supported the project.

This dataset contains water temperature, salinity, oxygen, currents and other data taken by CTD, Niskin bottles, and ADCP from the research vessel Keifu Maru, cruise KS19-06, in the north Pacific. The entire cruise was carried out during the period from July to September, 2019. Hydrographic observation was made using a Sea-Bird Electronics (SBE) 36 position carousel equipped with 10-liter Niskin water sample bottles, a CTD system (SBE911plus) equipped with JFE Advantech oxygen sensor (RINKO III) along 149E. Water samples were analyzed for salinity, dissolved oxygen and nutrients. Current data was measured by Teledyne RDI's vessel-mounted ADCP system (38kHz Ocean Surveyor). This dataset is U.S. State Department MSR U2019-007 as part of the World Data Service for Oceanography. Data are in PDF.
