Abstract:Hawaiian coastal waters have been, and continue to be, subject to major anthropogenic impacts
from land use changes, which have altered the characteristics of the coastal environment. This
study aims to investigate the effects of perturbations in the physical environment of a semienclosed tropical coastal embayment, Heʻeia Fishpond. A two-month time series of in situ
measurements within Heʻeia Fishpond captures multiple scales of variability of environmental
parameters. Instruments were deployed to observe the effects of invasive mangrove removal, and
by fortune, also observed the effects of three tropical storms. We explain the observed
environmental variability in terms of local and/or remote forcing, and investigate how physical
variability across a range of scales affects in-pond geochemistry and biogeography. As climate
change continues to increase sea surface temperatures the frequency of tropical cyclones is
projected to increase. It is critical to have an understanding of how increased temperature and
rainfall affect our coastal waters. With this understanding, areas like Heʻeia Fishpond can be
properly managed to mitigate future climate variability.
