Description

The National Data Buoy Center (NDBC), Stennis Space Center, Mississippi has issued a sources sought notice to locate suppliers and manufacturers of Conductivity, Temperature and Depth (CTD) sensors and inductive modem systems. Our goal is to gain insight into the market and identify potential small business sources. NDBC will procure instruments to provide real-time temperature, conductivity and pressure measurements of the ocean surface and subsurface from a sensor array connected via an inductive modem system on NDBC moored buoys. Hourly measurements will be polled and acquired by the buoy's computer from each sensor via the buoy's mooring wire and inductive modems at the sensors and at the surface. Each sensor shall be battery powered, with an internal clock and externally programmable deployment parameters and sampling schemes. Two configurations with two pressure/depth options of inductive modem instrumentation will be procured and should be separately identified as such by the vendor: The instruments will be deployed for periods up to 400 days at depths to 750 meters on mooring lines ranging from 3/8 inch OD-3/4 inch OD. Attachment shall be very simple and easily performed on the deck of a moving vessel. The mounts shall be streamlined and shall survive line strumming in the frequency range of 5 to 20 Hz. An internal, removable non-volatile memory storage system shall be capable of storing up to 50K samples of data, time, and battery voltage. Sample and data storage rates should be user selectable at rates of up to 1 Hz. Single samples or averages of samples shall be stored at rates of 5 seconds to 1 day. Internal battery packs shall have no hazardous material restriction, be easily replaceable, and support the sensor measurements and inductive communications up to 24 times per day for the deployment period. The integrated instruments cannot exceed 7.0 inches in width and 27 inches in length. Options for anti-fishing net/line devices with other dimensional and weight characteristics may be provided for evaluation. A single, highly corrosion resistant pressure vessel shall include the electronics, batteries, memory, and sensor mounting and shall have safety features that minimize the risk to personnel opening the cases by venting before disengaging. Communications shall be reliable, low-cost, low-power, real-time half-duplex ASCII data transmission via an inductive modem compatible with a DPSK (differential-phase-shift-keyed) protocol. Ease of conducting lab diagnostics, setup, and data extraction directly between the individual instruments and the surface inductive modem?s external connector shall be provided. The surface modem shall connect to the buoy's computer via an RS-232C interface. It shall use the buoy?s 8-20VDC power source at 60 ma maximum and shall be a single printed circuit card no larger than 4.5 by 6 inches. The surface modem connection to the mooring wire coupling device can be located up to 10 meters away. Windows 2000PC or notebook computer software, instructions, and documentation shall be provided for programming, test, data retrieval/processing, operation, and interface configurations with a graphical quick-look representation of all stored data for evaluation. The data formats shall be compatible with above communications specifications and GOES telemetry protocol or the vendor shall provide an estimate to develop an integral Government (NDBC) supplied format that is consistent with existing NDBC real-time shore processing Test plans, documentation, and test data for laboratory verification of the system operation, data processing, and accuracy shall be provided along with a listing of required equipment. Complete specifications can be found in the SOW at: http://www.ndbc.noaa.gov/business/procurement.shtml. Vendors are required to provide company information, point of contact, expertise, Federal schedule and product information in their response. All responses must be sent in writing by e-mail, mail, or fax. Address response to Dennis Morris, National Data Buoy Center, Building 1100 Room 360, Stennis Space Center, MS 39529. Fax number is (228) 688-3153. E-mail address is Dennis.Morris@noaa.gov.
