Blue Heron CTD Data Lake Superior and in situ Sonde field data Lake Erie Dataset Description: Methods and Sampling: <p>The CTD methodology applies to all data associated with Lake Superior and August Lake Erie. All of the other Lake Erie data is covered by the Sonde methodology.</p>
<p><strong>SeaBird Model 911 plus CTD profiler</strong></p>
<p>At each site, the SeaBird Model 911 plus CTD profiler was moved over the site using the A-frame at the rear of the <em>R/V Blue Heron</em>. The profiler was then lowered into the water and allowed to collect the data on the way down to the bottom of the water column. This is based on the water depth at each site, which ranged from about 7m to over 160m. Once at the bottom of the water column, the profiler was then raised back through the water column. During this process, the profiler was stopped at select water depths based on the site. This was done so the onboard 8L Niskin bottles could be used to collect the water at the selected sites. For each site, several casts of the profiler were necessary to collect the desired amount of water. Despite this, representative casts from each site during each cruise were selected to avoid unnecessary confusion and cluttering of the files with redundant data. The profiler produced two different data sets, marked as ASC1 and ASC2, both of which are&nbsp;included as supplemental files. The ASC1 files are continuous readings from the CTD as it moved through the water column. The ASC2 files is the same data set, but has been binned into 1m increments. Data from&nbsp;the ASC2 files were converted to Excel format and included in the main dataset, as that matches the data collected with the Sonde.</p>
<p><strong>Eureka Manta 2 Sonde</strong></p>
<p>At each site, the Eureka Manta 2 Sonde was placed into the water off the side of the <em>R/V Gibraltar III</em>. The Sonde was slowly lowered through the water column and was stopped every meter. At each meter increment the data readout from the Sonde was recorded into a notebook. The Sonde was lowered through the entire water column, but was only used to record water conditions on the way down through the water column. There are no associated raw files for this data, as the data was recorded directly from a real-time readout.</p>

Collaborative Research: Cyanobacteria, Nitrogen Cycling, and Export Production in the Laurentian Great Lakes
https://osprey.bco-dmo.org/project/891875
Collaborative Research: Cyanobacteria, Nitrogen Cycling, and Export Production in the Laurentian Great Lakes
<p><em>NSF Award Abstract:</em><br />
The Great Lakes hold about 20% of the freshwater on Earth and have been increasingly impacted by human activities in recent decades. Lake Erie suffers from large, annually recurring, toxic cyanobacterial blooms in summer, whereas Lake Superior experiences smaller, localized cyanobacterial blooms after storm events. Cyanobacterial blooms have harmful ecological, human health, and economic implications. These blooms are a global phenomenon, observed in lakes and oceans, and can lead to low oxygen conditions and the production of toxins, both of which can be harmful for ecosystems. Understanding how different types of cyanobacteria influence nutrient cycling remains a major knowledge gap. This project aims to provide a deeper understanding of the long-term state of the Great Lakes ecosystem. The research approach combines new and established methods. Project results and implications will be shared with local and regional water interests in partnership with the Pittsburgh Collaboratory for Water Research, Education, and Outreach, the Great Lakes Commission Harmful Algal Blooms Collaborative, and the Lake Erie Area Research Network. Education is a central part of this project and training opportunities target next generation of scientists, including postdoctoral, graduate, and undergraduate students. The students and postdoc will receive state-of-the-art training in the rapidly developing fields of biogeochemistry and geomicrobiology, while working with an interdisciplinary team of scientists.</p>
<p>This study will examine nitrogen cycling, phytoplankton community composition, and the nitrogen isotopic composition of chloropigments in order to evaluate cyanobacterial productivity in the modern Laurentian Great Lakes as well as the historical record of cyanobacterial blooms over the past several hundred years. The nitrogen isotope composition of chloropigments is expected to provide a powerful new proxy for understanding primary productivity and the relative importance of cyanobacteria to export production and nitrogen cycling. This proxy would be valuable not only for management of modern systems but has important implications for increasing our understanding of the role of cyanobacteria throughout Earth history. This project would test this molecular isotopic proxy in contemporary aquatic ecosystems to assess its efficacy for: (1) determining the relative contributions of cyanobacteria vs eukaryotic algae (e.g., diatoms) to primary production; (2) evaluating export production of cyanobacterial productivity (including blooms); and (3) constraining historical cyanobacteria productivity in the sedimentary record. Comparison of a system characterized by eutrophication and seasonal cyanobacterial blooms (Lake Erie) with one characterized by picocyanobacteria productivity, but the near-absence of large-scale cyanobacterial blooms (Lake Superior), will provide information about the range of impacts that cyanobacteria can have on carbon and nitrogen cycling. Further information regarding nitrogen cycling will be derived from analysis of solid and dissolved nitrogen species throughout the annual cycle, as well as seasonal studies of sediment processes to measure associated sediment nitrogen removal rates through different processes.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

SeaBird Model 911 plus CTD profiler
SeaBird Model 911 plus CTD profiler
PI Supplied Instrument Name: SeaBird Model 911 plus CTD profiler PI Supplied Instrument Description:At each site, the SeaBird Model 911 plus CTD profiler was moved over the site using the A-frame at the rear of the R/V Blue Heron. Instrument Name: CTD Sea-Bird SBE 911plus Instrument Short Name:CTD SBE 911plus Instrument Description: The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/
8L Niskin bottles
8L Niskin bottles
PI Supplied Instrument Name: 8L Niskin bottles PI Supplied Instrument Description:Once at the bottom of the water column, the profiler was then raised back through the water column. During this process, the profiler was stopped at select water depths based on the site. This was done so the onboard 8L Niskin bottles could be used to collect the water at the selected sites. For each site, several casts of the profiler were necessary to collect the desired amount of water. Instrument Name: Niskin bottle Instrument Short Name:Niskin bottle Instrument Description: A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc. Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/
Eureka Manta 2 Sonde
Eureka Manta 2 Sonde
PI Supplied Instrument Name: Eureka Manta 2 Sonde PI Supplied Instrument Description:At each site, the Eureka Manta 2 Sonde was placed into the water off the side of the R/V Gibraltar III. Instrument Name: Water Quality Multiprobe Instrument Short Name:Water Quality Multiprobe Instrument Description: An instrument which measures multiple water quality parameters based on the sensor configuration.
