Title: Variability of Winter-Spring Bloom Phaeocystis pouchetii Abundance in Massachusetts Bay.
Creator: David G. Borkman, P. Scott Libby, Michael J. Mickelson, Jefferson T. Turner, Mingshun Jiang
Abstract/Description: Abundance of the prymnesiophyte Phaeocystis pouchetii was quantified via light microscopy at 2-week to monthly intervals in Massachusetts Bay (southern Gulf of Maine, NW Atlantic) during 1992–2012. Variability in the abundance and seasonal cycle of Phaeocystis are described and synoptic hydrographic, nutrient, and meteorological data were analyzed to identify factors that may influence Phaeocystis abundance. The maximum Phaeocystis abundance was 14 × 106 cells L−1 (10 Apr 2008). It was...
Show moreAbundance of the prymnesiophyte Phaeocystis pouchetii was quantified via light microscopy at 2-week to monthly intervals in Massachusetts Bay (southern Gulf of Maine, NW Atlantic) during 1992–2012. Variability in the abundance and seasonal cycle of Phaeocystis are described and synoptic hydrographic, nutrient, and meteorological data were analyzed to identify factors that may influence Phaeocystis abundance. The maximum Phaeocystis abundance was 14 × 106 cells L−1 (10 Apr 2008). It was frequently (5 of 8 years) absent prior to year 2000, but not thereafter. Seasonally, it first appeared in February to early March, reached peak abundance in mid-April, and persisted until May or early June for a duration of 0–112 days (mean 34 days). A long-term alternation between Phaeocystis and centric diatom abundance was apparent, suggesting winter-spring selection of either Phaeocystis or centric diatoms. Phytoplankton community analysis suggested that blooms affected the rest of the phytoplankton community. Phaeocystis blooms were manifest as a substantial increase in particulate nutrients above normal levels. Phaeocystis blooms were preceded in February by a slightly elevated concentration of NO3 (9.3 vs. 6.5 μM when absent) and PO4 (0.99 vs. 0.79 μM when absent). Blooms were also preceded by elevated ratios of NO3/PO4, NO3/Si, and PO4/Si, and warmer, saltier waters reflecting reduced river discharge. The correlation with salinity and river discharge suggests that Phaeocystis bloom variability is partially determined by annually varying circulation processes that determine the degree of low nutrient, low salinity coastal water intrusion into Massachusetts Bay.

Title: Adaptive Decentralized Control of Mobile Underwater Sensor Networks and Robots for Modeling Underwater Phenomena.
Creator: Carrick Detweiler, Sreeja Banerjee, Marek Doniec, Mingshun Jiang, Francesco Peri, Robert F. Chen, Daniela Rus
Abstract/Description: Understanding the dynamics of bodies of water and their impact on the global environment requires sensing information over the full volume of water. In this article, we develop a gradient-based decentralized controller that dynamically adjusts the depth of a network of underwater sensors to optimize sensing for computing maximally detailed volumetric models. We prove that the controller converges to a local minimum and show how the controller can be extended to work with hybrid robot and...
Show moreUnderstanding the dynamics of bodies of water and their impact on the global environment requires sensing information over the full volume of water. In this article, we develop a gradient-based decentralized controller that dynamically adjusts the depth of a network of underwater sensors to optimize sensing for computing maximally detailed volumetric models. We prove that the controller converges to a local minimum and show how the controller can be extended to work with hybrid robot and sensor network systems. We implement the controller on an underwater sensor network with depth adjustment capabilities. Through simulations and in-situ experiments, we verify the functionality and performance of the system and algorithm.

Title: An Assessment of Potential Threats to Human Health from Algae Blooms in the Indian River Lagoon (USA) 2018–2021: Unique Patterns of Cytotoxicity Associated with Toxins.
Creator: Esther Guzman, Tara A. Peterson, Priscilla L. Winder, Kirstie T. Francis, Malcolm McFarland, Jill C. Roberts, Jennifer Sandle, Amy E. Wright
Abstract/Description: The Indian River Lagoon (IRL), a 156-mile-long estuary located on the eastern coast of Florida, experiences phytoplankton bloom events due to increased seasonal temperatures coupled with anthropogenic impacts. This study aimed to gather data on the toxicity to human cells and to identify secondary metabolites found in water samples collected in the IRL. Water samples from 20 sites of the IRL were collected during the wet and dry seasons over a three-year period. A panel of cell lines was used...
Show moreThe Indian River Lagoon (IRL), a 156-mile-long estuary located on the eastern coast of Florida, experiences phytoplankton bloom events due to increased seasonal temperatures coupled with anthropogenic impacts. This study aimed to gather data on the toxicity to human cells and to identify secondary metabolites found in water samples collected in the IRL. Water samples from 20 sites of the IRL were collected during the wet and dry seasons over a three-year period. A panel of cell lines was used to test cytotoxicity. Hemagglutination, hemolysis, and inhibition of protein phosphatase 2A (PP2A) were also measured. Cytotoxic blooms were seen both in the south (Microcystis) and the north (Pyrodinium) of the IRL. Each toxin induced a consistent pattern of cytotoxicity in the panel of human cell lines assayed. During blooms, cytotoxicity due to a single type of toxin is obvious from this pattern. In the absence of blooms, the cytotoxicity seen reflected either a mixture of toxins or it was caused by an unidentified toxin. These observations suggest that other toxins with the potential to be harmful to human health may be present in the IRL. Moreover, the presence of toxins in the IRL is not always associated with blooms of known toxin-producing organisms.

They are administered by the Smithsonian Institution and designed to enrich the literature on the history of aerospace and oceanography, and to contribute to "the increase and diffusion of knowledge among men." As a further tribute to the inventive genius of Mr. Link, it is appropriate that this, the seventh of the Link Lecture Series, be devoted to his development of the newest and most practical underwater work vehicle. The Johnson-Sea-Link submersible has just been commissioned and promises a great advancement in the area of marine research. For this achievement, also, we give immeasurable credit to J. Seward Johnson, whose financial contributions have helped in its construction, and will continue to help in its research operations.

Show moreFlorida is a tropical paradise that attracts marine enthusiasts and seafood lovers from around the world. Its extensive waterways not only offer unique areas for us to explore but also provide essential habitat for marine life. Although you cannot see them, marine bacteria are common throughout Florida waters. Marine bacteria play an important role in environmental processes by breaking down organic matter or providing food for larger organisms. There are many different species of bacteria that live in Florida waters. They are natural inhabitants of marine environments and live in and on many aquatic organisms. Under certain conditions, one type of marine bacteria known as Vibrio is capable of causing wound infections and seafood sickness in people with weakened immune systems.

Abstract/Description: Under certain conditions, one type of marine bacteria known as Vibrio is capable of causing wound infections and seafood sickness in people with weakened immune systems. Recently, the term “flesh-eating bacteria” has been used to refer to Vibrio. This description is false and misleading and causes unnecessary fear and panic. To ensure that your time on the water is safe and enjoyable, be aware of local hazards and follow these simple safety guidelines.

Title: CO 2 SCRUBBER DESIGN ANALYSIS FOR A MINI-SUBMARINE.
Creator: Wang, Tsen C., Harbor Branch Oceanographic Institute
Abstract/Description: The efficiency of CO2 scrubber performance is a function of temperature, pressure, gas mixture and density, co2 concentration and humidity in the gas stream, and scrubber design such as canister geometry, flow path, flow rate, resident time, absorbent packing methods, and the type of absorbent, etc. This paper describes the procedures to design the co2 canister volume, and minimum scrubbing rate for a CO2 scrubber in a submersible operation.
