New Insights on Abyssal Temperature Variations from the ALOHA Cabled Observatory

Above: Central North Pacific AABW Circulation and Topographic Constraints, from a presentation at Ocean Sciences Meeting 2016 [PDF]

Scientists working on the Hawaii Ocean Time-series (HOT) program have been making repeated observations of the hydrography, chemistry and biology of the water column at a station north of Oahu, Hawaii since October 1988 using the SBE 911plus CTD with SBE 3 temperature sensor and SBE 4 conductivity sensor. Data is compared on a monthly basis; the SBE 911plus CTD has provided consistent data over all these years.

The ALOHA Cabled Observatory (ACO), located in the Pacific Ocean 100 km north of the island of Oahu, Hawaii, has measured temperature variations at 4726 m (1.8 mab) in the Kauai Deep since June 2011. It provides real-time oceanographic observations from a depth of about 4,800 m via a submarine fiber optic cable that comes ashore at Makaha on Oahu. In addition to ocean sounds, continuous observations of temperature, salinity, and ocean currents are obtained and shared with the oceanographic community and the general public.

To learn more about new insights gained from the long term study, please view the following presentation [PDF] from the recent AGU/ASLO Ocean Sciences Meeting in New Orleans.


Multi-Parameter Water Quality Meter now available with pH


Sea-Bird Coastal introduces the HydroCAT-EP Multi-Parameter Water Quality Meter with pH.

The Sea-Bird Coastal HydroCAT-EP measures conductivity, temperature, depth, dissolved oxygen, pH, turbidity and chlorophyll. By plumbing the pH sensor in line with conductivity, temperature and optical dissolved oxygen, the HydroCAT-EP is capable of deployments up to three months without requiring data processing to correct for drift.

  • Advantages: Low Total Cost of Ownership, Annual calibrations, a Five Year Warranty, and Deployment Durations of Three Months mean less cost to service and maintain over the life of the instrument.
  • Data Reliability: EPA approved anti-foulants and pumped internal flow path provide maximum protection from bio-fouling. The quality of data output is maximized by limiting the potential impact of bio-fouling on sensors, virtually eliminating the need to post process the data to correct for drift.
  • Easy to service: The pH sensor is a smart sensor that can be hot swapped in the field, minimizing the need for in field service and calibration.

Sea-Bird 39plus Now Available with Inductive Modem Interface


Sea-Bird Electronics' new SBE 39plus-IM replaces the SBE 39-IM, first introduced in 2005. The SBE 39plus-IM provides a major electronics redesign with the following features:

  • Faster uploads via internal USB connector
  • Double memory capacity
  • Battery life increased by 50%
  • Easy-to-use USB software
  • Physically and Functionally interchangeable with existing IM moorings


Sea-Bird Scientific University

Sea-Bird Scientific offers regularly scheduled four-day training classes, approximately two times per year at an off-site location near our office/factory in Bellevue, Washington (12 miles/19km from downtown Seattle).

Here's a glimpse of our Sea-Bird University class from this past week.

Tech TipTech Tip: What software should I use with my instrument?

Sea-Bird Electronics
The Sea-Bird Electronics software package, Seasoft V2, consists of a number of individual programs. Install the entire package, or just install the program(s) that you need for instrument setup, data upload, real-time data acquisition, and data processing and plotting. Most of these programs work with a variety of Sea-Bird Electronics instruments.

Satlantic and WET Labs
Satlantic and WET Labs software is instrument-specific, and provide setup, data upload, processing, and plotting. Install the program applicable to the particular instrument you are working with (ECO, Cycle, Thetis, WQM, ISUS, SUNA V2, etc.)

Integration of Satlantic or WET Labs Instruments with Sea-Bird Electronics CTD

  • Doing the integration yourself? Use the applicable software to set up the Satlantic / WET Labs instrument. Then, update the CTD .xmlcon configuration file in Seasave V7 real-time data acquisition or SBE Data Processing CTD processing software. The .xmlcon configuration file tells the software what sensors are integrated on which channels of the CTD, and provides the calibration coefficients that allow the software to output data in engineering units.
  • Sea-Bird Electronics performing the integration at our factory? We set up the Satlantic / WET Labs instrument for its use with the Sea-Bird CTD. And then we create a .xmlcon configuration file consistent with all the sensors attached to your CTD.

For detailed information on all the software, see our 2016 Software Guide [PDF]
