keeping a toddler on a schedule seems to me a perfect reason to do away with daylight savings changes
🤧 A hefty plume of Saharan Dust will likely push into Florida by the weekend… This would lead to lower air quality and possible irritation of respiratory conditions. On the bright side, the dust is currently playing a large role in inhibiting tropical activity!
Dr. Harvey C. Hayes (as it turns out, a distant relation) worked for @USNRL in the 20th century; he had a Mid-Atlantic Ridge fracture zone named after him. Later @altagliabue et al. visited the site. My 1st PhD student, Neil Redmond, made a thesis chapter using it; what a world!
City Park Conservancy had the privilege to host students from @universitelaval (Quebec) Urban Planning for a presentation on Recovery Planning after a Disaster. Utilizing lessons learned from past storms, CPC is able to educate & learn from the future leaders in the industry. 📚
Graduate student @soseusm, Neil Redmond, wrote a children's book about using thorium in oceanography. Check it out! authorea.com/doi/full/10.22…
I'm excited to give a talk today @UofR . It's currently 7°F and the weather says something about "heavy freezing spray", but that's OK because we get to talk about the tropical Pacific!
