Tea bag decomposition experiment

PIs: Dr. Faming Wang, Dr. Jianwu (Jim) Tang, Marine Biological Laboratory

teabagWe use commercially available tea bags as standardized test kits to gather data on salt marsh decomposition rates. This is a cost-effective, well-standardised method. By using two tea types with contrasting decomposability, we can construct a decomposition curve using a single measurement in time. We will compare the decomposition rate within the high marsh and low marsh, and also in the warmed chamber versus ambient reference. Our data was also included in a worldwide cooperation network to investigate the decomposition rate in different ecosystems using the tea bag method.

Quantifying the Impact of Low Oxygen Conditions on Sediment Methane Fluxes in Waquoit Bay

PI: Wally Fulweiler, Boston University Marine Program
Funding: MIT-Seagrant

WallyThe negative consequences of excess nutrient loading alter estuarine sediment nutrient cycling in general and the production of methane in particular.  On a per molecule basis, the impact of methane on climate is over 20 times greater than carbon dioxide (over a 100 year period).  And even though estuaries make up a small portion of the total global ocean area they contribute about 10% of the total ocean methane emissions. Thus, quantifying how the production of methane in estuaries changes seasonally and spatially is an important step in our understanding of coastal systems and future climate. The purpose of this ongoing research is to quantify sediment methane production in Waquoit Bay, MA and to determine how low oxygen conditions alter these rates.  To do this we collect sediment cores at four sites exposed to varying oxygen conditions in the Waquoit Bay system and measure methane fluxes across the sediment-water interface. Additionally, we will conduct experimental manipulations where we alter the oxygen conditions in the overlying water to see how this impacts methane fluxes.

WBNERR Staff: Jim Rassman, Jordan Mora, Chris Weidman

Description: Sediment Elevation Tables (SETs) and benchmarks are used to measure change in marsh elevation with millimeter scale accuracy to determine sedimentation rates. This information, combined with accurate water level measures, can assess whether salt marshes are keeping up with sea level rise or risk being “drowned.” Traditionally SETs and benchmarks are installed by driving metal rods deep into the earth until they hit resistance. This can be difficult and costly as each 4’ length of rod is expensive. This project is investigating whether it is necessary to drive the rods that deep, or whether they are just as stable at, say, 20’ depth. Rods have been driven to different depths in the South Cape Beach salt marsh and are being “leveled” regularly – measured against a known point – to see if they have shifted. If not, this research could result in new standards for installation of this infrastructure which would save significant time and money. This is one of a growing number of projects in the new “Climate Change Observatory” in this marsh.

Late Holocene Marine Transgression and the Drowning of a Coastal Forest: Lessons from the Past

My research looks at coastal changes that have occurred in response to sea-level rise and storminess during the past 4000 years. I use a variety of methods including sediment core analysis, ground penetrating radar, GIS, and radiocarbon dating. Learning about how the Waquoit estuarine system responded to past sea level-rise and storminess will provide needed context for understanding and anticipating future changes.
An ancient red cedar forest was first revealed after a series of storms in 2010 resulted in significant erosion along South Cape Beach revealing 111 subfossil stumps along the beach and into the water. Thirteen stumps were radiocarbon dated and ranged in age from ~413-1200 years old. We assume this age represents the time at which the ancient trees were drowned by marine waters. Shoreline change analysis showed that between 1846 and 2008, the shoreline fronting the paleoforest retreated landward by 70 m at a long-term rate of 0.43 m/yr. paleo forest2
Sediment cores were analyzed to determine storm and sea level history. Radiocarbon dates of bivalve microfossils indicate that Waquoit Bay was first inundated by marine waters approximately 3600 years ago. The ongoing research will help decipher the relationship between sea-level rise, storminess, and the inundation of terrestrial ecosystems and will help to illuminate what caused the drowning of the South Cape Beach paleoforest.

Microbial Community Composition of Permeable Reactive Barriers – Who Is Really Doing the Work?

Jen BowenPIs:  Jennifer Bowen, UMASS-Boston

Funding: MIT Seagrant

Description: Permeable Reactive Barriers (PRBs) are currently being tested at the Waquoit Bay Reserve as a potential partial mitigation strategy for nutrient pollution. The barriers are designed to remove nitrogen by promoting microbially-mediated denitrification but there has been no examination of the microbial community that is responsible for the removal of the nitrogen and no attempt to understand how those microbial communities might respond to future environmental change.  This project will use molecular biology to examine how the barriers, and the periodic inundation of seawater, alter the structure and function of the microbial community. This information will help determine the best placement of the barriers to maximize their effectiveness.  Understanding how the microbial communities in the two barriers differ and under what environmental conditions the denitrifying bacteria thrive will help to guide future barrier construction, particular in the context of rising sea levels.

Development of Low-cost, In-situ, Precision Hydrodynamic Instrumentation for Measurement of Tides, Currents and Waves

Vitallii compressed

PI: Vitalii Sheremet, University of RI, NOAA NMFS Research Fellow

Funding: NOAA NMFS Research Fellowship, WBNERR collaborative in-kind

Description: An inexpensive current meter based on the drag principle is being designed and developed. It provides a simple, elegant, robust, and low-cost solution for measuring currents at the ocean bottom or from any fixed platform. Its operation is based on the drag law of a buoyant tethered cylinder in flowing water. Three-axis accelerometers measure tilts which are converted to a horizontal velocity vector. Special tethered attachment enables estimation of not only the magnitude but also horizontal direction of the current. The same accelerometers are also used to construct a simple stick-and-float tide gauge.

The performance of the instruments is being evaluated in field tests in Waquoit Bay and Nantucket Sound. Arrays of the instruments deployed for periods from days to months are used to record tidal and higher frequency oscillations in the Waquoit Bay. A dramatic double peaked flood (double height) tide arising from nonlinear interaction with bathymetry is studied. Strong seiches with periods of about 15-30 minutes are also recorded in some parts of the Waquoit Bay system.

Using Molybdenum Concentration in Estuarine Sediments as a Proxy for Hypoxia Occurrence and Frequency


PI: Warren Boothman (EPA)

Description: With the assistance of the Waquoit Bay Reserve, staff from the Atlantic Ecology Division of the U.S. Environmental Protection Agency’s National Health and Environmental Effects Research Laboratory are examining the relationship between the frequency of hypoxia (low dissolved oxygen) in marine waters and accumulation of molybdenum (Mo) in sediments underlying those waters. Previous research in Narragansett Bay (RI) has shown that Mo accumulates in sediments when the water above becomes low in oxygen and revealed a linear relationship between the total period of hypoxia and concentration of Mo in surface sediment. To test whether the relationship is valid over a wider spatial scale, the same analyses are being done at monitoring sites within Waquoit Bay that have more than a decade of water quality data. Research chemist Warren Boothman (EPA) and Chris Weidman, Research Coordinator at the Waquoit Bay NERR, collected 12 sediment cores from 4 sites in May that will be sliced into 1-cm thick sections and analyzed for Mo. Results of the chemical analyses will be combined with historical records of dissolved oxygen to determine whether the Mo-DO relationship found in RI is also valid in coastal water bodies in MA and presumably elsewhere. In addition to examining the Mo-DO relationship in recent years, vertical profiles of Mo in the cores could develop a historical perspective on the frequency of hypoxia in Waquoit Bay.

Nitrogen Fluxes to Waquoit Bay via Groundwater Discharge: Identifying End Member Concentrations

As groundwater flows to the coast, it meets and mixes with seawater. Mixing between these two water bodies creates a dynamic region-the coastal aquifer – where nutrients are chemically and biologically transformed. The fate of nutrients from development is a key issue in coastal areas like Cape Cod so understanding the processes in this area is of great importance.  The mixing zone beneath Waquoit Bay was monitored for three years to observe how it changes with different seasons and responds to climate events such as the 2009-10 El Nino.

Salt Marsh Productivity and Consumer Control in a Changing Climate

“The goal of my research at WBNERR is to investigate how Spartina alterniflora, the foundation species of salt marshes, will respond to rising temperatures, and to what extent salt marshes can resist drowning under predicted rates of sea level rise. Aboveground growth, in stems and leaves, and belowground growth, in roots and rhizomes, work in concert to maintain elevation and resist marsh drowning, and yet we don’t understand the patterns and processes driving the relationship of above to belowground growth. I am also exploring how the timing of flowering in Spartina influences elevation change and seed production. Understanding these mechanisms in salt marshes is critical to predicting potential loss of these ecosystems in the future.”

The Impact of Nitrogen-loading on Salt Marsh Greenhouse Gas Fluxes

Funding: MIT Seagrant
The general goal for the project is to measure potential greenhouse gas (GHG) emissions and net CO2 uptake in coastal wetlands under a range of realistic nitrogen (N) loads and inundation (sea) levels. By meeting this goal, we aim to improve the information with which managers and policy makers can maintain and maximize ecosystem productivity, reduce harmful feedbacks of climate, and assess the potential for these ecosystems to enter C markets.

We will examine how GHG emissions from salt marshes vary along an existing gradient of anthropogenic N loading in Waquoit Bay, MA (WB-NERR). Further, we will test for relationships between N loads to the marshes and plant productivity. To investigate the influence of anticipated future increases in sea level, we will use existing gradients in marsh soil elevation (and therefore a gradient in soil water saturation and in frequency and duration of soil inundation) as a space-for-time substitution simulating future inundation of soils.

Increasing atmospheric concentrations of three major greenhouse gases (GHG) are the main drivers of climate change. Efforts to ameliorate rising levels of GHG include the protection and restoration of ecosystems that constitute major carbon (C) sinks and minor sources of CH4 and N2O emissions. Tidal marshes are prime candidates for such efforts as their sediments display  high C sequestration. Loss of wetlands through human impacts such as land conversion, sediment supply disruption, nutrient loading, and with sea level rise, reduces future sequestration capacity and places at risk stores of C that built up over past centuries. Improved management of coastal C and nitrogen (N), based upon sound science, is a critical first step towards mitigation of climate change and management of coastal ecosystems. Management must address N loading that has the dual impact of 1) contributing to climate change through production of N2O, and 2) reducing production of root and soil matter by plants which can decrease the C sequestration capacity and resilience of marshes to sea level rise. Recognition of the importance of coastal marine systems in terms of C storage has led to national and international efforts to place monetary value on preserving or restoring the “blue carbon” in those systems, analogous to the value placed on forests. The barrier to incorporation of tidal wetlands into C markets is the absence of agreed upon GHG offset protocols that set guidelines for monitoring and verification requirements for wetlands projects, and a lack of data and knowledge regarding C and GHG fluxes in wetlands to support model development.

The project goals are to provide scientific information that can inform both C and N management as well as wetlands protection and restoration strategies for supporting development of policy frameworks and market-based mechanisms to reduce GHG.
