Long-term observations are essential for ecological research, providing insights into species and ecosystem variability, processes, and responses to change. In a time of rapid global change, ecosystem modification, and emerging threats, such long-term monitoring (LTM) is increasingly important.
Antarctic krill (Euphausia superba) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures…
A technique has recently been developed for tracking short-term spectral variations in Galactic cosmic rays (GCRs) using data from a single neutron monitor (NM)…
This paper presents the global analysis of two extended decreases in the galactic cosmic-ray intensity observed by worldwide networks of ground-based detectors in 2012. This analysis is capable of separately deriving the cosmic-ray density (or omnidirectional intensity) and anisotropy…
Observations of temporary Forbush decreases (FDs) in the Galactic cosmic-ray (GCR) flux due to the passage of solar storms are useful for space-weather studies and alerts. Here…
1. Marine invasive species can cause irreparable change in new environments, though not all non-native … species inevitably cause negative impacts to recipient … ecosystems.
The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021)…
Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging…
Background … Incomplete species inventories for Antarctica represent a key challenge for comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, functional traits…
We have considered TOMS (2000–2004) and OMI (2005–2021) total ozone column (TOC) data sets for the second part of winter cold period (January–March). Variations in both total ozone and characteristics of the Fourier wave harmonics with zonal numbers 1–5 are analyzed.
The Australian Antarctic Division (AAD)1 is undertaking planning activities for a proposal to construct and operate a new aerodrome near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project). The Davis Aerodrome Project would involve the construction of a 2.
Australia has decided not to proceed with a proposal to construct and operate a paved runway near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project), following careful consideration of the likely environmental impact, cost and complexity of the project.
Marine non-native species present an increasing threat to Antarctic marine ecosystems, particularly under climate change. This paper sets out progress with ongoing work initiated by the CEP Subsidiary Group on Climate Change Response (SGCCR)…
There is growing evidence that the Antarctic is increasingly exposed to chemical stressors. Antarctica is impacted by global issues such as climate change and long-range transport of chemicals. Furthermore, expanding tourism and research activities…
Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic ray intensity recorded with ground-based detectors also shows temporal variations arising from atmospheric variations.
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission … to promote international cooperation among research groups investigating the mesopause … region (80-100 km) with the goal of early identification of changing climate signals.
Zonal asymmetry in quasi-stationary ozone distribution is considered in the latitude range 50-80S using satellite total ozone data. Amplitude of the quasi-stationary wave has been determined as a half-difference between maximal and minimal values in 3-month averaged ozone distribution. Besides…
We analyse the precursor of a Forbush decrease (FD) observed with the Global Muon Detector Network on 2006 December 14. An intense geomagnetic storm was also recorded during this FD with the peak Kp index of 8+.
