Hi all. I recently got a cheapo $4 swimming pool / sauna thermometer. I've been playing with water temps for the fun of it, but I'm not sure I'm getting good readings, so I want to ask you how you do it (for those who do). Currently, I've got a lanyard attached to the thermometer, and I just drop it overboard and drag it along for about 10 minutes. When I drag it, it's only about an inch underwater. It's got holes in the top and bottom, so it gets water flowing through it as it's dragged along. Is that adequate? How do you do it?

I've never done anything like this, but I will mention that moving the thermometer will result in slightly different temperatures than keeping it still - think of wind chill. As well, the water temperatures can change dramatically with depth. The top layers can be significantly warmer due to sunlight absorption, rainfall etc, and can be warmed or cooled by wind. If you get more than a few inches down, the temp can drop a lot - however, it may vary more slowly over time. Therefore, measuring the temperature at the same depth is important if you want a realistic comparison from day to day. Measuring the temp profile with depth can be interesting - attaching the thermometer to a knotted line and measuring at each knot each time will show how temps change with depth over time. If you're on a boreal lake, you might even catch the seasonal turnover (I forget what that's called) if you measure year round.

>I've never done anything like this, but I will mention that moving the >thermometer >will result in slightly different temperatures than keeping it still - >think of >wind chill. > I may be wrong but I think the chilling factor has to do with the body loosing heat to try to maintain the surface temperature. The more wind the faster the surface is cooled down because there is more energy removed. The chilling factor affects living mechanisms that fight to keep the surface temperature. A body may need to send out 500 calories for a given static temperature or the same for a higher temperature but with wind, the wind conversion to the equivalent static temperature is the chilling factor. A thermometer will measure the temperature of the water moving since it does not have internal energy to supply to keep the surface temperature at a give value. The only temperature change might be due to heating by friction against the water which I think is so small that could be neglected. Therefore I think the reading should be very accurate of the average surface temperature which in a moving lake should take care of a couple or three feet depth, and is close to the temperature a capsized individual might feel in his face and body. As Mike says depending on the objective deeper measurements might be useful. I would be interested in teh close to surface temperatures anyway.

I want to clarify this - there's a bias in my thinking where I think of the thermometer initially at air temp with air temp higher than water temp. This need not be the case and the comment on wind chill might make you think that the moving thermometer would record a colder temp. The thermometer has to reach equilibrium with the water. A moving thermometer will reach equilibrium faster than one that is static, since the moving water will either carry away heat (warmer thermometer) or add heat (colder thermometer) more quickly. If you take a temp reading quickly, a moving thermometer will be more accurate. If you leave it immersed long enough, it doesn't matter. Since you are dragging it for 10 minutes, you're likely getting a good reading. The problem of depth still remains.

Ten minutes could be overkill, but it depends on the mass of the thermometer and how quickly it would reach equilibrium with the water. WRT depth, I think an inch is too shallow for nonmoving water. Surface temps can be appreciably higher on a lake than just a foot below. If you have swum in quiet water you'll have a sense of what I mean. Moving water in a stream can mix readily, so a surface temp might be representative. You might do either of two things. Put a weight on the end of the thermometer (maybe a coupla ounces) to keep it at a better depth, perhaps a foot. Alternatively (and I've done this on many occasions) take a goodsized mason jar and scoop up the water from a foot below and drop the thermometer in it. There won't be a significant temperature change for the length of time that you'll need for the thermometer/water system to equilibrate. --Done this kind of thing many times when working out dissolved oxygen readings...

I think you are on the right track with the phenomena of the moving Vs the static thermometer. To be more precise, the static thermometer is working by conduction only. The water in contact with the thermometer absorbs the heat from the thermometer and lowers its temperature to the water temperature while heating the water imperceptibly. When you move the thermometer you add convection to the cooling process and you are speeding the cooling process of the thermometer. All this assumes that the water is at the same temperature everywhere you move it and maybe this should be called an average temperature. The process of wind chill is a different mechanism. To really have wind chill you need to be moving air over a thermometer that can evaporate water off its surface continuously. This would be the "wet bulb" temperature. The cooling effect is augmented by the evaporation of the water out of the wet cloth and the temperature measured is actually less than the temperature of the air. This also applies to your body, wind chill causes you to cool by conduction, convection, and evaporation from your pores. It is hard to say that wind chill affects things that are dry like your car or your kayak on the roof. I don't think there is a water chill effect. Anyway, I'm ranting for no reason. Towing the thermometer quickly produces the same effect as holding it still provided all the water is at the same temperature. This makes me wonder why the weatherman gives us a "heat index" in the summer but doesn't deduct for a wind chill factor? *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

I have a stream thermometer on a lanyard with knots at 5' and 10' depths. I paddle out from the launch about 100 yards or so and stop, drop the thermometer to depth, and sit for about 3 minutes. Haul the thing in quickly and read it before the air can affect the temp. The 5' depth is my target, the 10' is just for fun to see the stratification in the water. I figure in a capsize you'll be sitting in the top 5' of water while you try to get back in the boat, so that's what's relevant for my purposes. I have tried to measure while under way, but as you have noticed trolling with your thermometer only gets you info on the top 2 inches. Since I haven't figured out how to stay at that level out of the boat it's not real meaningful to me. It depends on what you're after. Since I live on a large, deep (660') lake, it is subject to "lake turns", where the water temps can vary as much as 10-15 degrees F in a day's time when the lake "turns". Also, the direction of winds can greatly affect the surface temps. In my case, a strong sustained wind from the north blows in warmer surface water to my cove, where a sustained S-SE pattern (typical) will result in a gradual drop in temp over a couple days. These surface changes are only noticeable in the top 3-5 feet, the temp at 10' stays relatively constant. Enjoy, Jennifer Sign up for SBC Yahoo!

OK. I've taken the bait. What's a "lake turn" ? And why would a lake want to do that sort of thing ? regards, David *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

>OK. I've taken the bait. What's a "lake turn" ? And why would a lake >want to do that sort of thing ? Cooler water is more dense (actually, water is most dense at 4 deg C, decreasing in density when colder or warmer than this). Thus, most lakes are stratified with a lower more dense, cooler layer (the hypolimnion) and an upper less dense, warmer layer (the epolimnion). The boundary between these two layers is called the thermocline. The depth of the epolimnion grows during the warmer months. The density gradient resists wind-induced vertical mixing (thing of layers of oil and water). In the fall, the cooling of the epolimnion often results in the lake "turning over" --- this happens when the surface layer cools to the point where it is colder (read more dense) than the lower layer. In cold climates, the cooling of the surface water in spring associated with ice melt can produce another turn-over --- water at the bottom of the lake will be near 4 deg C; the melting ice cools the surface water to near this temperature; the lack of temperature stratification allows a wind-induced turnover (there isn't much resistance to vertical mixing because of the lack of stratification). See http://wow.nrri.umn.edu/wow/under/primer/page5.html for a more detailed description.

Hi Mike, I didn't mean to imply they were standard. I think 'standard' depends on the purpose. As I noted, the 5' depth is due to the fact that in a capsize you're going to be in the top 5' of water while you recover, so that's what I was interested in measuring. The 10' is just for fun to see the difference. I think 4" is too shallow to give an accurate picture of what you'll encounter out of the boat, but I may be all wet :). I'm sure the USGS has some standard for their stream guages, but I haven't checked yet.

Four inches is around the depth that I notice a change from warm surface water to colder lake water in many still lakes. I can see it being useful in a turbulent stream where there is little temperature stratification, but in lakes it would be next to useless. I wonder if two foot depth would be better for reflecting the depth at which a paddler would be affected - five foot would be at their toes; two foot, at their waist. > I'm sure the USGS has some standard for their stream > guages, but I haven't checked yet. They must have. Does NOAA have offshore weather bouys with temperature readings? I was paddling yesterday within sight of the following bouy on southern Georgian Bay: http://weatheroffice.ec.gc.ca/scripts/marinegen.pl?Client=ECMar_e&city=45143 The water was warm to a considerable depth compared to what I expect in the more northerly areas of Georgian Bay. The recorder temp was 17C but it felt much warmer where we were closer to shore.

I'm wondering why none of the 'gearheads' in this group have mentioned a remote sensing electronic thermometer. Radio Shack (here in the US) sells a cheap one with a 5 or 6 foot wire to the remote sensing element for under $10 USD and one that 'speaks' the temperature for under $20. A lead fishing weight for the remote element and you've got an instrument good to a tenth of a degree, C or F that you can read accurately while underway. You would, however, need to make some waterproofing modifications. I just thought of the last rolling/rescue practice I attended at the Chesapeake Paddler's Association in Annapolis, MD. I had my house and car keys tied inside my PFD. When I got home, I noticed the Princeton Tec pulsar light, powered by two small coin batteries, glowing weakly. I couldn't turn it off. When I took it apart, there was a tremendous amount of corrosion on the batteries, due to electrolysis in the brackish water we were in. Then I remembered another paddler who noticed that her car key would still unlock her car, but that she couldn't turn off the burglar alarm. It wasn't until I got home that I remembered that, and then thought that her car key also had a battery for the car alarm turn-off transmitter. -Kevin Zembower -- kevinz_at_charm.net Kevin Zembower On Sat, 6 Jul 2002, Jennifer Pivovar wrote: > --- Rick.Sylvia_at_ferguson.com wrote: > ...I want to ask you how you do it (for those who do). > > *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

>>>OK. I've taken the bait. What's a "lake turn" ? And why would a lake want to do that sort of thing ? regards, David It's part of the annual cycle of water in a large, mostly deep, lake. The word is "Turnover". As the weather warms and winds blow, the upper surface of a lake gets moved and heated. Sooner or later currents will set up in the upper layers from one side of the lake to another. This circulation tends to keep the accumulated heat and sediments, plankton, oxygen, etc. in that upper layer. The transition between the upper and lower layer is called the "Thermocline", a stratum where the temperature drops abruptly. Ever swim in a lake in nice warm temps then tread water and get your feet into something really cold? You just punched through the thermocline. The upper water cools as autumn/winter approaches, and at some point this thermocline barrier breaks down and the upper and lower layers mix; fairly abruptly and thoroughly. That's the Turnover. Check out a couple of texts on Limnology -- that's the science of water ecosystems. Much better descriptions than mine are available. Some general Ecology textbooks describe this as well.

That's the Turnover. Thanks Joe and Brian for the explanation. I suspected that dynamic from season to season . What threw me was when Jennifer said "Since I live on a large, deep (660') lake, it is subject to "lake turns", where the water temps can vary as much as 10-15 degrees F in a day's time when the lake "turns"." So I couldn't understand how the water could mix from top to bottom over a 24 hour period . At least not to a great extent. But I suppose there is some turning or turnover in the upper layers of the water between sun rise to sun rise going from a hot sunny day to a cool night air with the complete turn over from summer to winter . I often paddle on a local lake where I think the maximum depth is around 400 feet in the main part of the lake so I was well aware that the water temps drop dramatically only a few feet down.

Instead of wind chill the proper term is wet bulb depression. As water evaporates from the thermometer bulb it cools the bulb (heat of vaporization).
