Describe at least two factors that may have an effect on the water surface temperatures in days 1-30. Why are the surface temperatures different in 2019 & 2020 for days
1-30?

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
