Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.

Interpreter's Guide to the Finger Lakes Trail

Wed, 04/29/2015 - 21:44
Abstract: Guidebooks help hikers to navigate trail systems and gain a better understanding of their surroundings. Many types of guides exist for popular long distance hiking trails such as the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail. The Finger Lakes Trail (FLT) runs 558 miles across the base of New York State, yet has very little associated literature. I hiked a 52 mile section of the Finger Lakes Trail from Ellicottville to Portageville in western New York. Using observations from the trail and related literature, I wrote an interpretive guide for this section. My FLT interpretive guide covers topics related to planning and packing for a multiday backpacking trip, natural history of western New York forests, the story of the development of the FLT system, and backpacking ethics. This work will help satisfy the human need to acquire knowledge and potentially enrich the experience of FLT hikers.

Limnological Report of Marvin (Potters) Pond

Thu, 04/30/2015 - 09:51
Abstract: Long term data of limnological conditions is crucial to understand lentic freshwater ecosystems. Marvin (Potters) pond is a 2.04 hectare kettle pond located in Franklin County, New York in the Northern Adirondack Park. There have been numerous short studies of the pond over the past 30 years but the pond has never been intently monitored to date. The pond is assumed to be meromictic by the NYSDEC. The objectives of this study are to 1) calculate the morphometry of the pond and its watershed; 2) the determination of the trophic status of the pond; 3) to document the chemical composition of the pond, particularly as it relates to acidity and acid neutralizing capacity; 4) to document the annual dynamics of temperature and dissolved oxygen. Evidence from profile data on dissolved oxygen and total iron suggests that the pond is monomictic with the capability to be meromictic under certain climatic conditions. The mixing period of the pond occurred in the month of November. The morphometry of Marvin pond was found to have a conical cross sectional area and large depth for the surface area of the pond. The trophic state of Marvin pond was found to be eutrophic for chlorophyll-a and total phosphorus concentrations but mesotrophic for the secchi disk reading. The acidity of the pond was found to be high with a low buffering capacity.

Trophic status of Lake Placid over the past 2740 + 30 years inferred by sub-fossil diatom analysis.

Thu, 04/30/2015 - 11:07
Abstract: The hypothesis of this study was that human activity in the Lake Placid watershed would cause changes in the lakes trophic status. Trophic status was inferred by changes in diatom assemblages over time. This analysis shows that an unusual increase in Asterionella and Tabellaria has occurred within the past 200 years. Both of these species are indicators of higher trophic status, so their increase in numbers indicates a recent increase in trophic status (Stager 2001, Rawson 1956, Stevenson et al, 1982). Loss on ignition tests were used to determine the organic content of samples from two cores. These tests showed that organic content has varied in the past, however changes observed in the upper 20 cm of the record for Lake Placid and Wolf Lake suggest that human activity impacted the lake. The data collected in this study supports the hypothesis that human settlement in the Lake Placid watershed has changed its trophic status.

Effects of Reduced Turbidity and Suspended Sediment Concentrations on Macroinvertebrate Communities at a Restored Reach on Warner Creek

Fri, 05/01/2015 - 18:21
Abstract: A segment of Warner Creek, a tributary to the Stony Clove Creek in the Catskill Mountains of New York, was restored in 2013 to reduce concentrations of suspended sediment and turbidity caused by a localized mud boil erosion of a large clay bank. Before restoration, impaired water-quality from fine sediments may have adversely affected intolerant species of macroinvertebrates and their communities. This study compared macroinvertebrate assemblages from before (2011) and after (2014) restoration to determine if the restoration reduced concentrations of suspended sediment and turbidity sufficiently to improve the health of their macroinvertebrate communities. The New York State Department of Environmental Conservation (NYSDEC) kick-sample methods were used to collect four replicate benthic invertebrate samples from Warner Creek and from a reference site on the Stony Clove Creek during August of 2011 and August of 2014. Four replicates of 100 specimens were identified to the family level from each replicate. The NYSDEC Bioassessment Profile scores and selected macroinvertebrate community metrics and turbidity and suspended sediment concentrations from a USGS stream gage downstream of the restoration both pre and post restoration were evaluated to test hypotheses that water quality and the health of macro-invertebrate assemblages differed post-restoration. Although some families at Warner Creek with low tolerance values were found to have increased post-restoration, it was also found that others with moderate tolerance values decreased. These types of fluctuations were seen in both years at both Warner Creek and the reference site, which makes it impossible to definitively say the impact restoration had on the macroinvertebrate assemblages one year post restoration. At this time it is obvious from the stream gage data that restoration significantly decreased turbidity and suspended sediment concentrations (SSC). Further collection of invertebrates and stream gage comparison is necessary to see if restoration does eventually impact the assemblage of invertebrates.

Building Families Stronger

Tue, 05/05/2015 - 14:05
Abstract: The purpose of this study is to design a program that can be implemented in local camps to accommodate the needs of individuals in a family group affected by mental illness. The study will explain the importance of educating individuals about mental illness and integrating supportive behaviors. This program is designed to help families cope with the effects mental illness can have on the entire family dynamic. Families are often the strongest support system for dealing with mental illness and educating families is essential for success of the mentally ill. Team building games are used to enhance social behaviors and encourage group bonding, this program uses a recreational therapeutic approach to addressing issues in the lives of those affected by mental illness. To figure out how many people will be most likely be using the therapy program, a survey was created using a series of questions that went with the topic for respondents to answer. In fact the survey established that the majority of people agree on recreational approach to therapy as a means of coping with their illness in real life tasks. Other questions asked was what their favorite activities where, such as paddle sports and hiking. Another question was what disability was so as to get an idea what accommodations would be need and services for patients involved with the program.
