Understanding Causes and Impacts of the Dinoflagellate, Cochlodinium polykrikoides, Blooms in the Chesapeake Bay
Margaret R. Mulholland,Ryan E. Morse,George E. Boneillo,Peter W. Bernhardt,Katherine C. Filippino,Leo A. Procise,Jose L. Blanco-Garcia,Harold G. Marshall,Todd A. Egerton,William S. Hunley,Kenneth A. Moore,Dianna L. Berry,Christopher J. Gobler +12 more
TL;DR: Bioassays determined that C. polykrikoides exerted a lethal affect on juvenile fish and shellfish, causing 100% mortality of juvenile fish (Cyprinodon variegates) in less than 24 h and 20% mortality in juvenile American oysters within 72 h.

Kevin D. Friedland,Colleen B. Mouw,Rebecca G. Asch,A. Sofia A. Ferreira,Stephanie A. Henson,Kimberly J. W. Hyde,Ryan E. Morse,Andrew C. Thomas,Damian C. Brady +8 more
TL;DR: In this article, a change-point statistics algorithm was used to detect phytoplankton blooms in time series (1998-2015) of chlorophyll concentration data over a global grid.
Regime shifts in fish recruitment on the Northeast US Continental Shelf

TL;DR: In this paper, the authors analyzed stock assessment output and survey data to test for regimes in the recruitment success of 18 commercially important marine species over a 29-year timespan, and found evidence for three decadal-scale recruitment regimes: low recruitment success in the 1980s, high success in 1990s, and a return to low recruitment performance in the 2000s.
Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods
Kevin D. Friedland,Nicholas R. Record,Rebecca G. Asch,Trond Kristiansen,Vincent S. Saba,Kennneth F. Drinkwater,Stephanie A. Henson,Robert T. Leaf,Ryan E. Morse,David G. Johns,Scott I. Large,Solfrid Sætre Hjøllo,Janet A. Nye,Michael A. Alexander,Rubao Ji +14 more

TL;DR: It is suggested that either grazing is a factor in shaping the seasonal bloom or bloom shape determines whether a habitat is conducive to diapause, while recognizing that both factors can re-enforce each other.
Trends and change points in surface and bottom thermal environments of the US Northeast Continental Shelf Ecosystem
Kevin D. Friedland,Ryan E. Morse,James P. Manning,Donald Christopher Melrose,Travis Miles,Andrew G. Goode,Damian C. Brady,Josh Kohut,Eric N. Powell +8 more
TL;DR: In this paper, the authors studied the effect of temperature on the productivity and organization of marine ecosystems, in particular, continental shelf ecosystems, which are responsible for much of the world's food security.
