Article Synopsis
  • The Southern Ocean features dynamic mesoscale eddies that significantly influence global biogeochemical cycles, yet their overall effects on biogeochemistry have not been fully explored.
  • Research aligns these eddies with data from biogeochemical Argo floats, revealing that anticyclonic eddies (AEs) lower dissolved inorganic carbon (DIC) and nitrate, while cyclonic eddies (CEs) increase these concentrations; dissolved oxygen also varies significantly between the two types of eddies.
  • AEs and CEs play a role in the Southern Ocean's carbon uptake, with AEs contributing 0.01 Pg C while CEs offset this contribution by the same amount, highlighting the need to consider eddy effects in climate models

The Centers for Disease Control and Prevention's (CDC's) Global Rapid Response Team (GRRT) was created in 2015 to efficiently deploy multidisciplinary CDC experts outside the United States for public health emergencies. The COVID-19 pandemic dramatically increased the need for domestic public health responders. This study aimed to follow up on previously published data to describe the GRRT surge staffing model during the height of the COVID-19 response.

Background: Asymmetry of the aortic valve leaflets has been known since Leonardo Da Vinci, but the relationship between size and shape and origin of the coronary arteries has never been examined. Our aim was to evaluate this anatomy in a population of pediatric patients using a cross-sectional study design.

Methods: Consecutive pediatric patients with trans-esophageal echocardiography (TEE), with or without trans-thoracic echocardiography (TTE), were included in our study.

Modeled water-mass changes in the North Pacific thermocline, both in the subsurface and at the surface, reveal the impact of the competition between anthropogenic aerosols (AAs) and greenhouse gases (GHGs) over the past 6 decades. The AA effect overwhelms the GHG effect during 1950-1985 in driving salinity changes on density surfaces, while after 1985 the GHG effect dominates. These subsurface water-mass changes are traced back to changes at the surface, of which ~70% stems from the migration of density surface outcrops, equatorward due to regional cooling by AAs and subsequent poleward due to warming by GHGs.
