The East Siberian Sea is an area of high biogeochemical activity caused by multiple factors, such as an influence of river runoff, Atlantic, and Pacific waters, formation and melting of sea ice, and internal circulation. Extensive amounts of carbon a

Zooplankton identification has been the subject of many studies. They are mainly based on the analysis of photographs (computer vision). However, spectroscopic techniques can be a good alternative due to the valuable additional information that they

A comparison of two LIBS systems (CCD vs. ICCD) with compact DPSS laser to a benchtop XRF system was carried out to estimate the practicality and the advantages of both methods for in situ quantification of the Fe/Mn ratio in ferromanganese nodules.

Modern analytical techniques, including laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy, yield multidimensional data, which are most efficiently used in conjunction with chemometric techniques, including multi-block algorithms. In

The iron oxide ‘orange arc’ bands are unambiguously detected in persistent meteor trains, meteor wakes, and clouds, as well as in the terrestrial airglow. In contrast to the majority of other astronomically important diatomic molecules, theoretic

Laser-induced breakdown spectroscopy (LIBS) is considered as a method for elemental analysis of concrete in situ. However, the content of chlorine responsible for corrosion of the iron reinforcement may be lower than the LIBS sensitivity needed to de

Ratios of light metals (Li, Na, K, Mg, and Ca) in zooplankton (Calanus spp.) were determined by laser-induced breakdown spectroscopy without reference samples under the assumption of local thermodynamic equilibrium. The temperature of plasma formed a

Low intensity lines of elements with high excitation potentials, especially non-metals, is one of the main problems of laser-induced breakdown spectroscopy (LIBS). To our knowledge, we report the first combination of long spark produced by a cylindri

Spatial confinement of laser-induced plasmas has been recognized in the last decade as one of the ways to enhance the sensitivity of trace detection. However, there is no clear explanation for the fact that some lines are enhanced while others, in co
