Some probes that I am familiar with (at least schematically) use a weighted, bullet-shaped head to sink the probe through the water column, taking salinity and temp measurements on the way down. When a certain depth is reached, a data package is released and floats to the surface for collection, while the rest continues to the bottom. not sure of the physical size of the apparatus. recovery is not easy in high seas, so I definitely see the advantage to being able to reel a probe back in.
I was thinking along the same lines, Ann. I would also like to know more about the actual data collection aspect - types of probes, how the sensing mechanisms work and what parameters are able to be measured, as well as how the data is collected and stored...this looks like a very interesting system!
I'm curious about the relative size, weight, cost and other metrics and characteristics of the probes currently in use, to give some context for the discussion of the deployment system. For example, what size and weight are now used in current probes, vs the lighter weight and more compact size aimed at here? Also, how would the probe be designed or constructed differently so it is reusable instead of disposable?
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
