Sampling

We took samples for chemistry and biology and did in situ measurements with the hydrolabs for depth and salinity.

The hydrolab measurements were used later for calculation of flux of groundwater and seawater into ponds.

We also carried out a microscale experiment looking at the salinity of the top centimeters of Kaloko pond. Sampling all night long (see part 3) and taking manual measurements of microlayers from kayaks turned work into fun.

Notice the hydrolab dangling from a stick to measure salinity, dissolved oxygen, Ph, temperature and depth.

Data, data, and more data.

More hydrolab sampling without the stick.
