Science (photo shoot) in action. #SANDLab does beaches @ucsantabarbara with @topomaddie @nitzanswet @UCSBgeog

[Ian J. Walker @ij_walker]

@deepseadawn Yes! I wholeheartedly agree! There is only one solution…

Recent storm impacts on our Santa Barbara beaches. Impressive efforts underway to deliver sediment from upland retention basins. Unfortunately, these pics portend a future scenario the state asks us to prepare for... +3.5' of sea-level rise by 2050 @UCSBgeog @MSI_UCSB

Quantifying wind dynamics, sand transport, and dust emissions in complex terrain is tough. Recipe = CFD + field verification + teamwork. Creative science solutions to solve air quality problems at Oceano Dunes! https://t.co/zrfFEFLcKr. @DRIScience @UCSBgeog @ODSVRA_PSB @GeoHilgy

[Ian J. Walker @ij_walker]

Curious about #NatureBasedSolutions for coastal #restoration and how to evaluate success? New study on foredune restoration to solve longstanding air quality problem, Oceano Dunes, California. Team effort! @UCSBgeog @DRIScience @GeoHilgy @ODSVRA_PSB https://t.co/akZSHu3v0N

Come join us @UCSBgeog! We have an info session on graduate school admission (Nov 9).

@envirogeography Is a tweet a learning outcome? Whatever… good times and lots of learning to be had at #oceano #dunes today for our GEOG288 #coastal geomorph class!@UCSBgeog @envirogeography

Here's where California’s cliffs are collapsing into the sea the fastest https://t.co/0JNLPfIGyi

@Jon_Warrick Sure do @Jon_Warrick. Notable impacts on beach morphology and sed budgets, esp if #aeolian processes are prevalent https://t.co/yJDmhGbIXW https://t.co/EdaX6vxsk2 @UCSBgeog

@TrisalynNelson Oh my. Time to step away from the screens @TrisalynNelson
