The paper describes a recommendation of a coordinate system to be used in all biological disciplines to report observations, agreed on by the natural history museums and the scientific societies in Finland. In the recommended coordinate system, the p-axis of the Cartesian coordinate system joins the E 27° longitude. The recommendation describes in detail how the observations are reported using this system.

The article is a travel report of the author’s travel from Helsinki to north of Finland. Alongside the description of the travel arrangements, it contains observations about the vegetation of the destinations they visited. The observations are divided into section of “spruce region”, “pine region” and “fjeld region”.

We describe here a study based on analysis of vegetation indices and land surface temperatures, which provides relevant information for estimating soil moisture at regional scales. Through an analysis of MODIS satellite imagery and in situ moisture data, the triangle method was used to develop a conceptual land surface temperature−vegetation index model, and spatial temperature-vegetation dryness index (TVDI) values to describe soil moisture relationships for a broad landscape. This study was situated mainly within two states of the southern United States (Georgia and South Carolina). The total study area was about 30 million hectares. The analyses were conducted using information gathered from the 2009 growing season (from the end of March to September). The results of the study showed that soil moisture content was inversely proportional to TVDI, and that TVDI based on the normalized difference vegetation index (NDVI) had a slightly higher correlation with soil moisture than TVDI based on the enhanced vegetation index (EVI).
