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

Here's where California’s cliffs are collapsing into the sea the fastest

A new study pinpoints erosion hot spots along the entire California coast — and found that cliffs in Northern California are disappearing the fastest.

"Air flow and sediment transport dynamics on a foredune with contrasting vegetation cover" Read how wind flow dynamics differ between native and invasive vegetation dunes in ESPL (@BSG_Geomorph) with @ij_walker @MikeGSilentT @alanaradd onlinelibrary.wiley.com/doi/… #coasts #dunes

Air flow and sediment transport dynamics on a foredune with contrasting vegetation cover

The influence of two adjacent, vegetation canopies on modifying wind flow and sediment transport potential on a foredune during the same wind event are examined. The taller and denser Ammophila...

Dear university administrators everywhere. Please pick a lane and stay in it with #LearningManagementSystems. My career journey, spanning 3 institutions: Moodle-Blackboard-Canvas-Moodle-Blackboard... now Canvas. I think I see a pattern here.

Two #mountainbiking #geomorphologists come upon a rock exposure. One says to the rock face, "What cracks you up?". The other says, "I hypothesize that carbonate precipitation and wetting/drying cycles does." Hence, a paper was born. doi.org/10.1016/j.catena.202… @UCSBgeog @ASU_SGSUP
