Extraordinary methane levels in a small bar‐built tropical estuary
Abstract Small estuaries link uplands and nearshore marine environments but are understudied in many regions. We quantified spatial and temporal variability in CH4, CO2, nutrients, and organic matter in a small, deep, bar‐built tropical estuary in Fajardo, Puerto Rico.

Abstract Methane (CH4) accumulation in the oxic metalimnion is a common yet poorly resolved feature of deep stratified lakes. In Lake Geneva, lateral transport from the Rhône delta has been suggested but lacks spatial validation. Here, we quantify the role of lateral advection in shaping metalimnetic CH4 using high‐resolution in situ CH4 measurements ...

Abstract Reef fish have complex life cycles where pelagic larval survival and recruitment are linked to environmental and early life history traits (ELHTs). We combine light traps and otolith microstructure analysis to examine how environmental variables and ELHTs drive larval growth and settlement in the endemic Ophioblennius trinitatis.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

ABSTRACT During the late 20th and early 21st century three conceptual revolutions reordered our understanding of the history of the Earth: The spread of plate tectonic theory from the 1960s onward which brought geology the first meaningful theory for building mountains and the migration of continents; the rebirth of catastrophism in 1980 with the ...

Abstract This study investigates the projected nonstationary behavior of extreme total water levels (ETWL) and extreme coastal water levels (ECWL) along the Southeast Asian coastline under the high‐emission climate scenario. Using a high‐resolution seamless projection data set of storm surge and ocean waves forced by MRI‐AGCM3.2, combined with regional

Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.
