Size group (pico, nano, micro) and group total carbon estimates from cell counts via epifluorescent microscopy (EPI) of heterotrophic and autotrophic plankton from CCE LTER process cruises in the California Current region, 2006 - 2016
Microbial community assemblages of the California Current Ecosystem (CCE) are assessed for biomass of heterotrophic (dinoflagellate and other eukaryotes) and autotrophic (dinoflagellate and other eukaryotes) plankton using high-throughput digital epifluorescence microscopy (EPI). Samples to estimate the nano- and microplankton (0.2-2.0-µm and 2.0-20-µm size, respectively) are collected at various depths, preserved, stained, and filtered onto a membrane filter and mounted on a glass microscope slide aboard the process cruises (since 2006, ongoing). Slides are then frozen at -80°C for subsequent imaging and analysis in the laboratory onshore. Carbon biomass is computed from cell biovolumes.
Picophytoplankton and bacteria total carbon estimates from cell counts analyzed with flow cytometry (FCM) from CCE LTER process cruises in the California Current region, 2006 - 2017.
Picophytoplankton populations and non-pigmented prokaryotes are sampled within the California Current Ecosystem (CCE) for abundances from various depths. Seawater is collected from Niskin bottles and cells are fixed in the field aboard the survey cruises (since 2004, ongoing) with paraformaldehyde, and stained with a DNA-specific dye back in the laboratory. The cells are enumerated by an Altra flow cytometer (with a syringe pump for volumetric sample delivery) simultaniously with argon ion lasers, to distinguish three major populations of photoautotrophs (Prochlorococcus, Synechococcus, and pico-eukaryotes) and the assemblage of heterotrophic prokaryotes collectively referred to as H-Bact. FCM abundance estimates for each are converted to carbon biomass equivalents using mixed-layer estimates.
Soil Carbon and Nitrogen analysis:Effects of white pine invasion of old fields on biogeochemical processes
Woody plants are invading many grassland regions of the central US. At Cedar Creek, white pine (/Pinus strobus/) is successfully invading many old fields. This project aims to determine the influence of white pine invasion on biogeochemical processes.
Process exploration and assessment for the production of methanol and dimethyl ether from carbon dioxide and water
<p>A thermodynamic, model-based, study was carried out to assess the relative performance of methanol and<br> dimethyl ether (DME) synthesis systems using CO- and CO2-based syngas feeds. The upstream production<br> of a range of syngas feed compositions was simulated using CO2 and H2O as the sole chemical building<br> blocks, a requirement motivated by the increasing constraints on permissible CO2 emissions and the<br> successful adaptation by some industrial methanol plants to the direct utilisation of CO2. The objective<br> was to establish whether the energy requirements and CO2 emissions associated with upstream<br> conversion of CO2 to CO were justified by increased productivity in the methanol/DME systems. In the<br> first part of the study, the performance of four systems was evaluated and compared in terms of energy<br> efficiency and CO2 conversion: (1) methanol synthesis system, (2) direct DME synthesis system, (3) twostep<br> DME synthesis system with an interposed syngas separation step between the methanol production<br> reactor and methanol dehydration reactor and (4) two-step DME synthesis system with no separation<br> step between the two reactors. Based on equilibrium yields at 250 oC and 50 bar, the direct DME<br> synthesis system was found to exhibit the highest energy conversion efficiencies with both CO2- and<br> CO-based syngas. Although this system demonstrated the lowest CO2 emissions per methanol<br> equivalent product with a CO-based feed, the benefits were offset by emissions associated with the<br> upstream conversion of H2O and CO2 to H2 and CO, evaluated in the second part of the study. It was<br> determined that CO2 could be utilised directly in the direct DME synthesis route, whereas upstream<br> conversion of CO2 to CO was necessary to achieve effective yields in the methanol/two-step DME<br> systems. CO-based syngas production via high temperature co-electrolysis of H2O and CO2, or<br> alternatively high temperature CO2 electrolysis coupled with the water–gas shift process, was identified<br> as the best technology based on energy consumption and CO2 utilisation.</p>

Carbon:234Thorium ratios of sinking particles collected by sediment trap and large particles collected by in situ pump on CCE-LTER Process Cruises. 2006 - 2017 (ongoing).
The ratio of carbon to 234Thorium on particles can be used to convert water column 234Th measurements to sinking carbon flux estimates and to investigate particle scavenging in the ocean. Carbon:234Th ratios of two types of particles are measured: true sinking particles collected by sediment trap and large (>50-µm) particles collected using a McLane in situ Pump. Sinking particles are collected in VERTEX-style particle interceptor traps (PIT) with an 8:1 aspect ratio, 70-mm diameter, and a baffle on top comprised of 13 smaller beveled tubes with a similar 8:1 aspect ratio. Tubes are deployed with a formalin-brine for a duration of 2-5 days. After recovery, samples were gravity filtered through a 200-µm filter. The 200-µm filtered was then immediately examined under a stereomicroscope and mesozooplankton swimmers were removed from the sample. On P0704, P0810, and P1106 cruises the remaining (non-swimmer) portion of the material on the >200-µm filter was then re-combined with the <200-µm portion of the sample. Samples were then filtered through a pre-combusted quartz (QMA) filter. On P1208, P1604, and P1706 cruises the >200-µm and <200-µm fractions were filtered separately onto QMA filters to determine C:234Th ratios of different size classes of sinking particles. Typically, triplicate whole PIT tubes were filtered for C:234Th ratios. However, on some cycles with very high flux, samples were first split on a Folsom splitter. On some cycles, the mesozooplankton ‘swimmers’ were saved and filtered onto a separate QMA filter to quantify the C:234Th ratio of mesozooplankton. QMA filters were all dried and mounted in RISO sample holders. >50-µm particles were also collected using McLane in situ pumps (typically deployed for a period of ~1 hour at the same depth of the sediment traps). In situ pump samples were rinsed off of the 147-mm nitex mesh filters used with the pump onto a pre-combusted QMA filter, which was similarly dried and mounted in a RISO sample holder. Samples

Carbon Capture, Utilisation and Storage systems analysis through cognitive mapping - elicitation process
<p>Carbon Capture, Utilisation and Storage (CCUS) projects are complex systems due to their multistakeholder and multisectoral nature. Therefore, We consider it crucial to propose a holistic approach to evaluate CCUS systems by using participatory processes to capture the complexity between technical, environmental and social structures interaction. We can achieve this by building cognitive maps, which represent people's knowledge and perceptions of CCUS projects.</p> <p>In CCUS systems, we deal with complex problems involving many parties and conditions without a unique or suitable solution for projects implementation. Albeit many components interact in the projects, we can select the most representative to represent the system. This research seeks to collect various cognitive maps from different stakeholders, which will be integrated later to analyse how physical-technical components interact with socio-political ones.</p> <p> </p>
