Background:
In the open ocean, water temperature varies with depth in the
mixing layer (nominally 30 metres deep). In a ship's wake, the
temperature gradient in the wake is different from the
surrounding water body due to the mixing of the sea water by the
propeller. 

Defence Research and Development Canada (DRDC) is currently
conducting research on the thermal characteristics of the wake
of a ship.  This research initiative includes the measurement of
water temperatures in the wake.  Therefore, to conduct this
research, DRDC needs to acquire several devices that can make
these water temperature measurements at different depths in the
mixing layer as well as collect other information like sea water
salinity.  DRDC also requires any associated services to
transmit select data to a base station and parse that data into
a useable form.  Detailed Mandatory requirements for the devices
are provided in Annex A of the Solicitation document.  

Requirement:
A ship's wake measurement trial will be conducted in July/August
2015.  During the trial, a ship (likely larger than 20 m in
length) will travel in a straight line in coastal waters at
different speeds.  At the beginning of and during each run, the
measuring devices will be deployed from the stern of that ship
(see Figure 1).  The devices, as best as possible, need to drift
with the ship's wake.  The devices will be recovered by the
trial vessel about 60 to 90 minutes after deployment.  Select
data from the devices needs to be transferred to a base station
via an Iridium satellite link while the devices are deployed. 
Two different types of devices are required:

a. a device that drifts with the wake and measures water
temperature at the sea surface and at various depths (i.e., a
water temperature measurement device); and, 
 
b. a device that drifts with the wake and measures sea surface
temperature and ocean salinity (i.e., a water surface
measurement device).

The solicitation document contains complete details on the
requirement and the bid evaluation and contractor selection
methodology.


Delivery Date:
All the deliverables to be received 6-8 weeks from date of
contract award. 


Basis of selection:  
A bid must comply with the requirements of the bid solicitation
and meet all mandatory technical evaluation criteria to be
declared responsive. The responsive bid with the lowest
evaluated price will be recommended for award of a contract.
