“…Cranberry and Long Pond spectra both show increased chlorophyll spectral character due to active algal and macrophytic growth. This is especially advanced in Long Pond which has been accelerated by phosphorus loading from Northrup Creek, a primary tributary draining 23.5 2of agricultural and housing developments including a waste water treatment plant (Sherwood 1999).…”

Hyperspectral analysis tools for the multiparameter inversion of water quality factors in coastal regions

A major modeling effort has been undertaken to develop and refine tools for extracting water quality parameters from remotely-sensed hyperspectral imagery. An outgrowth of this work is HydroMod, a new tool for calculating radiance distributions using realistic environmental conditions for studies involving remote sensing of water quality. HydroMod mates two established premier codes, MODTRAN and HYDROLIGHT. The idea is to simulate the water-leaving spectral. radiance above and below the surface for varying inputs of water quality parameters. Spectral measurements can then be compared with this family of model predicted water-leaving spectral radiance vectors to find a best match and subsequently the associated water quality parameters that were used to generate the matching curve. The scope of the modeling analysis has been limited to the water-leaving radiance in the vicinity of the surface instead of the radiance reaching the sensor. Once the modeling technique using HydroMod has been refined, the atmospheric correction problem over water can be addressed with greater probability of success and fewer sources of uncertainty. This paper will describe the preliminary results from the model-based approach applied to AVIRIS data of a littoral zone and plans for future refinements in the modeling physics.

Yellow Perch (Perca flavescens) inhabit both nearshore and coastal wetland habitats of the Laurentian Great Lakes throughout their lifetime and are known to exhibit different movement life histories. However, uncertainty persists in the spatial extent of this variation and in the duration of habitat use. To explore these uncertainties, we used a multi-metric approach that included water and otolith microchemistry and tissue stable isotope ratios (δ13C, δ15N). The ratio of manganese to calcium in otoliths was used to identify transitional movements between nearshore Lake Ontario and wetland habitats while carbon and nitrogen tissue isotope ratios revealed variable duration of wetland inhabitance. Our research suggests that the multi-metric approach was useful for addressing questions that could not be answered by one method alone. Our results demonstrate individual differences in duration of coastal wetland habitat residence among Yellow Perch, which may influence their susceptibility to recreational harvest. As Yellow Perch are an important species of consideration for management agencies such as the Great Lakes Fishery Commission, exposing such diversity is important when considering the potential for differential contributions of individuals with variable movement life histories to overall population stability and resilience over time.

Megacollect 2004: hyperspectral collection experiment over the waters of the Rochester Embayment

This work describes the water collection experiment component of the Megacollect 2004 campaign. Megacollect was a collaborative campaign coordinated by RIT with several institutions to spectrally measure various target/background scenarios with airborne sensors and ground instruments. An extension to the terrestrial campaign was an effort to simultaneously measure water optical properties in different bodies of water in the Rochester Embayment.This collection updates a previous effort in which water surface measurements were made during an AVIRIS mission over the Rochester Embayment (May 1999). Megacollect 2004 builds on this through an expanded campaign that increased the number of stations sampled, extended the spectral range of measurements, and improved the spatial resolution of the imagery through the use of multiple sensors (COMPASS, SEBASS, MISI, WASP). A larger set of in-water instruments were deployed on several vessels to sample and measure water optical properties near the shores of Lake Ontario, the northern portions of Irondequoit Bay, and several smaller ponds and bays in the Rochester Embayment. This paper describes the different in-water instruments deployed, the measurements obtained and how they will be used for future modeling efforts and development of hyperspectral algorithms.

Phosphorus loads entering Long Pond, a small embayment of Lake Ontario near Rochester, New York

Abstract: Reductions in the amount of phosphorus in discharge from the Spencerport wastewatertreatment plant have decreased phosphorus loads in Northrup Creek and led to the improvement of water quality in Long Pond.
