DESCRIPTION:Presenters: Simon Freeman (ARPA-E) & Daniel Rogers (ARPA-E)\n\n
 This seminar is an outreach effort seeking to inform the ocean sciences an
 d sensor development community about ARPA-E and the upcoming SEA-CO2 progr
 am. This program seeks to accelerate the development of the marine Carbon 
 Dioxide Removal (mCDR) industry through the development of Measurement\, R
 eporting and Validation (MRV) technologies.\n\nMRV must be of sufficient q
 uality to quantify carbon drawdown magnitudes\, the degree of permanence\,
  and bound the uncertainties associated with these parameters so that carb
 on markets can ascertain credit quality and financial institutions can mak
 e informed decisions regarding investment risk. mCDR will be an essential 
 component of a future negative emissions industry\, that alongside emissio
 ns reduction is necessary in restricting climate warming to less than 2°C
  in order to avoid global\, irreversible\, and catastrophic changes caused
  by this temperature rise. To achieve these goals\, a paradigm shift is re
 quired in chemical oceanographic data collection from today’s sensors ca
 pable of accurate measurements at individual point locations\, towards a g
 oal of persistent sensing at equivalent accuracies across large areas and/
 or volumes.\n\nTechnical progress is required in two areas: 1) The develop
 ment of persistent\, radiated energy-based (i.e.\, optical\, acoustic\, el
 ectromagnetic) chemical oceanographic sensor technologies that enable larg
 e-scale volumetric or swath quantification of mCDR-relevant ocean chemical
  parameters\, beyond depths sensed by satellite systems\, to transform our
  fundamental understanding of the ocean carbon cycle\, quantify mCDR effic
 acy\, and to reduce or eliminate under-sampling concerns that limit carbon
  credit quality. 2) The development of regional-scale\, ocean carbon flux 
 models that integrate and estimate the combined major carbon cycles (i.e.\
 , physical\, inorganic chemical\, micro and macro-biological) likely to be
  impacted by one or more mCDR approaches in the region. Models will be dev
 eloped under this program to first achieve state-of-the-art performance le
 vels for bias and variance before application to estimate the impact of ne
 w sensing technologies on carbon flux quantification accuracy\, and thus c
 redit quality. Models will also be developed as a basis for a data-driven 
 carbon accounting framework.\n\nSample Technological Approaches/Questions:
 \n1. Acoustics: High-frequency active underwater acoustic sensor developer
 s. Can a high-frequency ADCP or another high-frequency array be modified t
 o capture variations in the acoustic impedance of seawater\, possibly reve
 aling water properties in 3D after correlation and validation\n\n2. Optics
 : Underwater spectroscopy through either backscatter or absorption that co
 uld work on spatial scales of ~1-100m. Approaches could include Raman\, i.
 e.\, not just elemental but molecular characterization. Particular interes
 t in time-gated backscatter techniques\, as those would give range resolut
 ion.\n\n3. Electromagnetic sensing. Technology being demonstrated by some 
 (e.g. Twinleaf) is so sensitive. Could it be used to characterize the minu
 te variations in local EMF created by (i) seawater composition (ii) seaflo
 or sediment composition (iii) the many millions of living things per m^3 o
 f seawater\, including microbial as well as macro-organisms?
