Optimizing stereo‐baited remote underwater video sampling efficiency in turbid waters through horizontal field of view adjustments

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate length data underpin many ecological and physiological analyses, from assessing population size structure to parameterizing biomass and bioenergetic models. Stereo‐baited remote underwater video systems (stereo‐BRUVs) provide a non‐intrusive means of collecting these data in situ, supporting management and conservation of motile ...

A systematic 15N‐amino‐acid tracer framework to identify sources of pelagic marine organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurately tracing organic matter sources in marine systems remains challenging, particularly where natural and anthropogenic inputs coexist. Compound‐specific stable isotope analysis of amino acids (CSIA‐AA) offers strong potential for organic matter source discrimination, but its application is limited by the small number of validated δ15N ...

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Purse seining for small pelagic fish around Sri Lanka

open access: yes, 1975
An attempt has been made to study skipjack (Katsuwonus pelamis) live bait availability and other small pelagic fish, their seasonal variations with respect to distribution, species and size composition. Exploratory surveys made use of echo sounding and lookout during the day, and light attraction at night.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...
