Four methods commonly used to count phytoplankton were evaluated based upon the precision of concentration estimates: Sedgewick Rafter and membrane filter direct counts, flow cytometry, and flow-based imaging cytometry (FlowCAM). Counting methods wer

Determining the viability of protists and small microzooplankton has long been a focus of studies in marine biology and ecology. It is especially relevant in the issue of shipborne invasive species, and impending international guidelines and various

The pitting corrosion resistance of surface-modified 316L austenitic stainless steel and N08367 (a “superaustenitic” stainless steel) were evaluated in 0.6 M NaCl solutions and compared to untreated samples of the same materials. The surface modi

Experiments were performed whereby steel specimens in natural seawater were successively cathodically polarized, depolarized or partially depolarized, and then repolarized to simulate the life cycle and retrofit of a galvanic cathodic protection (CP)

The historical development of marine cathodic protection design, along with the recently developed, first-principles-based slope parameter method, is reviewed briefly. It was projected that the remaining issues that require resolution before cathodic
