Workshop goals

The aim of this workshop is to push forward our knowledge of extreme weather and fire effects on coastal carbon cycling. The workshop will bring together a diverse group of scientists to build a community of monitors/observers, experimentalists, and modelers to address these challenging knowledge gaps across these spatial and temporal domains. Confirmed plenary speakers for the workshop are as follows (by theme):

Storms: Ken Kunkel (NOAA), Kevin Reed (Stony Brook Univ.), Lisamarie Windham-Myers (USGS)

Ecosystems: Greg Noe (USGS), David Lagomasino (ECU)

Modeling: Julia Moriarty (Univ. Colorado), Douglas Hamilton (Cornell), Nick Ward (PNNL)

Wildfires: Erin Hanan (UNR), Sasha Wagner (RPI)

Workshop Logistics

This workshop, and all OCB activities, will adhere to the OCB code of conduct. All participants should read this before the workshop, and report any incidences that occur.

All participants should receive an email on acceptance, along with a decision on travel support requests by August 26. Contact us if you did not receive an email (check your spam folder first).

FLIGHTS: All participants (except invited speakers and organizers) should arrange their own travel to NC (best airport is Raleigh-Durham International Airport (RDU). Flight costs are very high, so book asap.
Organizers & invited speakers: Sarah Herring (UCAR) is arranging flights, do not book your own flights. Sarah is also arranging mileage reimbursement for organizers/invited speakers traveling by personal car.

LODGING: Participants will stay at the Holiday Inn - Raleigh Downtown (320 Hillsborough Street, Raleigh, NC 27603), unless you live locally. OCB will arrange a block and pay for hotel reservations for all participants for the nights of Oct. 23, 24, 25 (checkout on Oct. 26). If you need to stay longer contact Mary (not the hotel) to arrange an extension - you will need to pay for any additional nights.

GETTING AROUND: You are responsible for getting from the airport to the hotel (participants can self-coordinate on this ride-share sheet). There will be a workshop bus for transportation between the meeting space and hotel daily. There will also be an option to take a organizer-led scenic walk to the meeting venue (40 minutes) each morning. For the Sunday night mixer before the workshop, a mix of carpool and rideshare will be arranged on the spot.

MEETING VENUE & MEALS: The workshop will take place at NC State Campus - breakfast and lunch will be catered each day (with a low-carbon plant-based & local focus), dinner on your own Sun and Tues. A welcome reception and poster session Sunday night will have appetizers. On Monday a casual gathering at a diverse food court near the hotel will allow everyone to pick from numerous eateries and network in small groups. The workshop will conclude with a grab&go or enjoy on site box lunch on Weds.

POSTERS: Vertical layout is required due to the posterboard dimensions. Your poster must be no larger than 32" wide and 48" tall. {poster list coming soon}

COVID PROTOCOLS: Health and safety are a priority. For its activities, OCB typically requires N95 or similar masks to be worn in enclosed spaces (auditoriums, buses, breakout rooms, poster sessions, etc.) during the workshop, except when eating. However, we cannot require masking per updated NCSU COVID guidelines, so we are strongly encouraging participants to use masks to ensure the collective comfort, health, and safety of all. We also request that you bring with you several rapid tests and take a test before meeting the group Sunday evening, and if you feel sick at anytime. We will Zoom stream plenary sessions for online participants, also so if during the week you start to feel ill at any point you can stay in your hotel and watch the workshop.
Order free rapid tests here (US residents).


Climate change is fundamentally altering coastal carbon cycles, by altering linkages among the land-air-water spatial domains. These alterations have been documented for the past 20-30 years due to increases in extreme weather events (fires, drought, tropical cyclones). Conceptually, these events are episodic and represent pulses experienced by the affected ecosystems, as opposed to the gradual presses (sea level rise, land use change), often under which the pulses occur. Responses to these events can reorganize coastal carbon cycles by translocating enormous amounts of carbon and nutrients (e.g., N and P) stored in coastal landscapes to the coastal ocean via biogeochemically active terrestrial-aquatic interfaces: river corridors, riparian and tidal wetlands, etc. In addition, these pulses can also transport microorganisms capable of driving biogeochemistry (Kominoski et al. 2020). However, these responses exist within time domains that are poorly understood and not constrained in coupled biogeochemical or Earth system models (Ward et al. 2020).

The aim of this workshop is to push forward our knowledge of extreme weather and fire effects on coastal carbon cycling. This OCB Scoping Workshop will bring together a diverse group of scientists to build a community of monitors/observers, experimentalists, and modelers to address these challenging knowledge gaps across these spatial and temporal domains.

The following conceptual questions serve as a framework to achieve the workshop’s goal:

  • What soil and hydrologic schematics (e.g., “Pulse Shunt Concept”, Raymond et al. 2016) do we adapt that span the aquatic continuum and how do they interact with sea-level rise?
  • How do we build OC degradation and replacement rates across the continuum, along with C-nutrient-microbe interactions fueling autochthonous production and sequestration?
  • How can we incorporate foodweb dynamics and community compositional changes across the continuum?
  • How do we acknowledge and incorporate the importance of comparative analysis across the continuum in response to extreme events?
  • What models are best suited to capture and link residence times of C and nutrients in wetlands/soils and estuaries (receiving waters)?
  • How can we increase our capacity for "biogeochemical storm chasing" (building on meteorological model) through regional networks of observations?
  • What international collaborations are needed to constrain the diversity of coastal environments and be coordinated to resolve larger scale feedbacks by which extreme events are coupled to ocean-climate phenomena like ENSO, which can exacerbate fires on one continent and cyclones on another?
  • How do we ensure that we have the relevant seconds/minute/hour-scale measurements to capture these events with in situ and remote sensing observation platforms?
  • How do we integrate Eulerian and Lagrangian observations?
