Estimate how much the salinity of the surface water of the Arctic Ocean would need to increase before the surface density would equal the potential density at 1000-m depth. how does this compare with the average salinity of the ocean? (Good values might be T=-1.5˚C, S = 32.8, and potential density about 24.5.)

A student wishes to find the concentration of an unknown saltwater solution, so they prepare a series of saltwater solutions of known concentration and measure their conductivities and the conductivity of the unknown. They then plot a calibration curve of conductivity versus concentration for the known solutions. Given the variables of saltwater concentration and saltwater conductivity, which would be the independent variable and which would be the dependent variable, if applicable? Saltwater concentration is the dependent variable, saltwater conductivity is the independent variable. There is not enough information to answer this question. Saltwater concentration is the independent variable, saltwater conductivity is the dependent variable. Both variables are independent and there are no dependent variables given. Both variables are dependent and there are no independent variables given.
