Optimisation and control of tidal range power plants operation: Is there scope for further improvement?

open access: yesEnergy Conversion and Management: X
Tidal barrage power plants utilise the tidal range variation to generate clean electricity. Although there are several operating tidal barrage schemes around the globe, there is still potential to expand the installed capacity.

Cheia de axé (full of axé): Spirituality, resistance, and repair in Pernambuco's Afro‐Brazilian traditional communities

open access: yesFeminist Anthropology, EarlyView.
Abstract This article explores how Afro‐Brazilian communities in Pernambuco respond to state‐led industrial development through culturally rooted practices of resistance and repair. Drawing on archival and ethnographic research in the coastal municipalities of Cabo de Santo Agostinho and Ipojuca, this study traces the effects of Brazil's large‐scale ...

Characteristic Analysis of Vertical Tidal Profile Parameters at Tidal Current Energy Site

open access: yesJournal of Marine Science and Engineering
Many mathematical models have been proposed to estimate vertical tidal current profiles. However, as previous studies have shown that tidal current energy sites have different characteristics in their vertical tidal current profiles, it is necessary to ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Radical Uncertainty and New Sector Emergence: An Action Theory of Co‐Creative Stakeholders

open access: yesStrategic Change, EarlyView.
ABSTRACT For much of the past century, entrepreneurship scholars have sought to understand and assess the nature, role, and impact of uncertainty. While the sum total of this work has contributed valuable insights, radical uncertainty—characterized by dynamic conditions in which outcomes are unknowable at the time action must be taken—remains weakly ...

Indirect effects of fast‐growing urban development on wildlife in a coastal protected area of Costa Rica

open access: yesThe Journal of Wildlife Management, EarlyView.
We studied the effects of urban growth on wildlife near Parque Nacional Marino las Baulas, Costa Rica. Since 1991, buildings increased 1007%, mainly in the buffer zone. We identified eight native species extracting garbage from containers, with raccoons (Procyon lotor) comprising most detections (84%), and four other species being potential sea turtle ...

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

PNNL‐TUNAMELT: Toward automating the detection of interactions with marine energy devices using acoustic camera sensors

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.
