Hello Everyone This Is An Image Of The Antisana

Hello everyone,

This is an image of the Antisana volcano in Ecuador.  IG Ecuador collaborated in a project to understand the water reserve in the Andean moors.

Best wishes

Top Of The Day Agu Fans Taking You To The High

Top of the day AGU fans!

Taking you to the high Canadian Arctic are Anna Grau Galofre (Twitter: @agraugal - Arizona State University Exploration Postdoc) and Shannon Hibbard (Twitter: @Shann0nMars - Western University PhD Candidate). Anna and Shannon are riding off into the sun on their fat tire bikes to dig some baseline trenches across ice-wedge polygon troughs located on the eastern side of Axel Heiberg Island, NU, Canada. Anna and Shannon are geophysicists who use Arctic landscapes as analog environments for places like Mars. Together the two have spent 6 field seasons in the high Canadian Arctic pursuing their research on topics like distinguishing subglacial channels from fluvial ones, and what is the so called “brain” terrain. The trip was led by Gordon Oz Osinski (Twitter: @drcrater - Western University Director of the Institute for Earth and Space Exploration) and A. Mark Jellinek (University of British Columbia), also joined by Antero Kukko (Twitter: @KukkoAntero), Chimira Andres (@RocksNRockets) and Etienne Godin. Enjoy!

Dear Agu Community Hello From Our Pre Covid

Dear AGU community,

Hello from our pre-COVID field work from 2019! My name is Emil Cherrington, and I’m a Research Scientist with the Earth System Science Center at the University of Alabama in Huntsville (UAH). For our first Postcard from the Field, we wanted to share with you a collage of photos and other images related to our ongoing NASA-funded “Climate-influenced Nutrient Flows and Threats to the Biodiversity of the Belize Barrier Reef Reserve System” (BZ-SDG) project. In a nutshell, our project involves collaborating with stakeholders in Belize to use satellite data - calibrated using field observations - to monitor the country’s coastal and marine water quality, hence the pictures of water. This work is in support of the Government of Belize's Sustainable Development Goal (SDG) commitments, particularly regarding SDG 14 (“life below water”). Our project is one of a suite of projects that NASA is supporting in the framework of the Group on Earth Observations (GEO)‘s Earth Observations for the Sustainable Development Goals (EO4SDG) initiative.

Sending Holiday Wishes From The Kuruman Banded

Sending holiday wishes from the Kuruman banded iron formation in the Griqualand West Basin, South Africa. This photo was taken during my time as a field demonstrator for a Geology undergraduate class (I can never say no to a good field trip🙂). Loving the view from here and I hope you do too!

Buoy Completes A Decade Of Lake Observing Science

Buoy completes a decade of lake observing science

Dear Everyone:

The Muskegon Lake Observatory buoy (MLO; www.gvsu.edu/buoy/) completed a decade of time-series weather and water quality data acquisition in this Great Lakes estuary in 2020 – delayed, but not defeated by the ongoing pandemic. Muskegon Lake is a model urbanized Great Lakes estuary that is impacted by legacy eutrophication, harmful algal blooms, and bottom water hypoxia, and the MLO serves as a sentinel that monitors water quality improvements during ongoing ecosystem restoration. Here, we are on board NOAA­–Great Lakes Environmental Research Laboratory’s R/V 5501 (buoy tender) retrieving the buoy from the lake after its 10th year of operation, assisted by NOAA crew members Beau Breymer, Todd Roetman, and Dan Burlingame. MLO continues to provide valuable long-term, time-series, open-access data (~10 million as of today) on estuarine ecology in the Great Lakes, allowing us to share observations and discoveries that have relevance to natural waters in inland and coastal zones everywhere that are similarly affected by anthropogenic forces and climate change.

Salut Were Writing From The Beautiful Salt

Salut!

We’re writing from the beautiful salt marsh of La Pocatière, Quebec on the St. Lawrence estuary. We’re measuring greenhouse gas fluxes from different zones of the salt marsh. The picture shows Sophie (a post-doctoral fellow at McGill University and the University of Birmingham, UK) installing gas flux chambers on the mudflat. Between coring, collecting porewater, clipping vegetation, and trying to get it all done before high tide, we are tired! We’re so grateful to be in the field and not stuck at home in lockdown, especially after changing fieldsites and experiments due to COVID-19 restrictions. Good luck to everyone during these trying times wherever you’re working from!

A la prochaine,

Lake Observing Science Continues In A Pandemic

Lake observing science continues in a pandemic

Dear Everyone:

Despite the delay caused by COVID-19-related work restrictions and safety protocols, we were finally able to deploy the Muskegon Lake Observatory buoy (MLO) to gather time-series weather and water quality data in this Great Lakes estuary.  Here, we are making use of an improvised pontoon boat with a winch and a moon pool for docking to the buoy and servicing the infrastructure.  Water Resources technician, Tony Weinke (left), is securing the panel that covers sensitive data loggers on the big yellow buoy that serves as the main work platform, power source, met station  and communication center; and Aquatic Science graduate student, Nate Dugener (right), is working to link the soon to be submerged daughter buoy carrying an array of water-quality sensors (in blue) with the main buoy.  Now in its 10th year of operation, MLO continues to provide valuable long-term time-series open-access data on estuarine ecology in the Great Lakes www.gvsu.edu/buoy/

Our First Sampling Campaign On The Rv Belgica

Our first sampling campaign on the RV Belgica after Corona pandemic confinement was from 22-24 June. Although social distancing and wearing of masks remains obligatory, we were able to continue the monitoring of suspended particles and dissolved substances in the Southern Bight of the North Sea. The aim is to understand better the variations on tidal, seasonal and inter-annual scales that occurs due physical forcing (tides, meteorology, climate), biological cycles (algae blooms), biogeochemical processes (carbon and nutrient cycles) and human activities (eutrophication, contaminants, dredging and dumping activities, offshore constructions). The monitoring includes water sampling for the analysis of the total suspended matter, organic suspended matter, chlorophyll and chemical pollutant concentrations and is carried out in three stations located along the cross shore gradient from the high turbid nearshore to the low turbid offshore waters.
