Mount Pinatubo and Atmospheric Extinction at Mount John University Observatory 1987-94 [PDF]
Atmospheric extinction in the V passband at Mount John University Observatory, New Zealand, from 1987-94 is presented and the effect of the 1991 Mount Pinatubo volcanic eruption is discussed.

Abstract Harmful algal blooms caused by toxin‐producing species of the diatom genus Pseudo‐nitzschia have been linked to anomalously warm ocean conditions in the Northern California Current System. This study compares summertime concentrations of Pseudo‐nitzschia spp.

Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.

The solar towers of Chankillo [PDF]
An ancient solar observatory is composed by thirteen towers lined on a hill of a coastal desert of Peru. This is the Chankillo observatory. Here we discuss it, showing some simulations of the local sun direction. An analysis of the behaviour of shadows is also proposed.

Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season
Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.

Energy Poverty: Measurement and Governance in Europe and Lessons for Australia
Abstract In Australia there is limited understanding of the scale and nature of energy hardship or poverty. Energy poverty remains a concept with no clear definition and therefore no clear objectives, targets, metrics for data collection nor institutions to monitor and report on.

Abstract The expansion of autonomous observation platforms offers vast opportunities for analyzing ocean ecosystems and their role in carbon export. As part of the EXport Processes in the Ocean from RemoTe Sensing campaign, we autonomously measured the productivity regimes in two contrasting end‐member ecosystem states.

Empirical Evidence on the Incidence and Persistence of Energy Poverty in Australia
Abstract Energy poverty is a temporary condition, yet a non‐negligible share of the Australian population suffers persistent energy disadvantage. Using the Household, Income and Labour Dynamics in Australia (HILDA) survey, we observe that single individuals, single‐parent households and those with a disabled household member are at high risk of ...
