Today is Sunday and there is no work today. I thought I would take the time to introduce you to 2 instruments we use when collecting water samples. One of them is called a Niskin bottle. It is simply a device that is used to collect the water. It is held open at both ends by cords, then lowered into the water. Once at the desired level, the lids are triggered to close and the water is collected inside. Then the water is dispensed to various containers for testing. Another tool is a water probe that records data as it is slowly lowered into the water. The device will record temperature, salinity(salt content), and Ph to name a few things.
