A new LA-MIC-ICP-MS analytical technique has been developed for the rapid measurement of 206Pb/238U zircon age (<1%, 2s) at a high spatial resolution. We show that this technique can be routinely employed to date U–Pb in small and/or complex zircons, providing a powerful tool for geochronology.

Abstract. Measurements of the microphysical properties of mixed-phase clouds with high spatial resolution are important to understand the processes inside these clouds. This work describes the design and characterization of the newly developed ground-based field instrument HOLIMO II (HOLographic Imager for Microscopic Objects II). HOLIMO II uses digital in-line holography to in-situ image cloud particles in a well defined sample volume. By an automated algorithm, two-dimensional images of single cloud particles between 6 and 250 μm in diameter are obtained and the size spectrum, the concentration and water content of clouds are calculated. By testing the sizing algorithm with monosized beads a systematic overestimation near the resolution limit was found, which has been used to correct the measurements. Field measurements from the high altitude research station Jungfraujoch, Switzerland, are presented. The measured number size distributions are in good agreement with parallel measurements by a fog monitor (FM-100, DMT, Boulder USA). The field data shows that HOLIMO II is capable of measuring the number size distribution with a high spatial resolution and determines ice crystal shape, thus providing a method of quantifying variations in microphysical properties. A case study over a period of 8 h has been analyzed, exploring the transition from a liquid to a mixed-phase cloud, which is the longest observation of a cloud with a holographic device. During the measurement period, the cloud does not completely glaciate, contradicting earlier assumptions of the dominance of the Wegener–Bergeron–Findeisen (WBF) process.

AbstractAn on-wafer micro-detector for in situ EUV (wavelength of 13.5 nm) detection featuring FinFET CMOS compatibility, 1 T pixel and battery-less sensing is demonstrated. Moreover, the detection results can be written in the in-pixel storage node for days, enabling off-line and non-destructive reading. The high spatial resolution micro-detectors can be used to extract the actual parameters of the incident EUV on wafers, including light intensity, exposure time and energy, key to optimization of lithographic processes in 5 nm FinFET technology and beyond.

Environmental context. There is a need for slightly invasive techniques capable of in-situ probing of target analytes in environmental compartments. Owing to its passive sampling mode and small probe dimensions, microdialysis-based dosimetry is an appealing tool for monitoring of solute concentrations in both water bodies and pore soil waters with minimum disturbance of natural equilibrium. The development of field applications is challenging but will provide novel insights as to the speciation and bioaccessibility of environmental pollutants, e.g. trace metals, at high spatial resolution. Abstract. In-situ sampling of soil pore water is still a challenge for environmental scientists. Here, microdialysis is explored for probing metal concentrations in soil pore water at soil moisture contents ranging from 50 to 115% of the maximal water holding capacity and is compared with traditional sampling by suction cups. Metal concentrations obtained by the suction cup technique were consistently larger than those measured in the dialysate. Good agreement was obtained for Pb and Cu at soil moistures close to saturation after accounting for diffusion resistances whereas corrected Ni and Cd concentrations in the dialysates exceeded those measured by the suction cup technique. These deviations reflect inherent differences in the sampling mode and effects of soil heterogeneity at the microscale. Microdialysis offers new opportunities to probe solute concentrations at high spatial resolution and minimal disturbance of soil conditions at environmental interfaces such as the plant rhizosphere or at the transition between forest floors and the mineral soil.

&lt;p&gt;&amp;#160;&amp;#160;&amp;#160; The term &quot;fine scales&quot; is generally used to refer to the ocean processes occuring on horizontal scales smaller than 10 km and&lt;br&gt;characterized by a short lifetime (days/weeks). Fine scales have been predominantly studied with numerical simulations and&lt;br&gt;satellite observations which have highlighted their significant role on biological processes. Indeed, their short time scale is the&lt;br&gt;same as a lot of important processes in phytoplankton dynamics. Model simulations have shown that fine scales such as fronts&lt;br&gt;and filaments strongly influence the distribution of phytoplankton species. Nowadays, the combination of in situ measurements,&lt;br&gt;satellite observations and model simulations is a necessity to better understand these mechanisms. However these processes&lt;br&gt;are particularly challenging to sample in situ because of their size and their ephemeral nature.&lt;/p&gt;&lt;p&gt;&amp;#160;&amp;#160;&amp;#160; The PROTEVSMED-SWOT cruise was performed in the Western Mediterranean Sea, in the southern region of the Balearic&lt;br&gt;Islands, onboard BHO Beautemps-Beaupr&amp;#233;, between April 30&lt;sup&gt; th&lt;/sup&gt; and May 14 &lt;sup&gt;th&lt;/sup&gt; , 2018. In order to study the influence of fine&lt;br&gt;scales on the distribution of phytoplankton species, a satellite-based adaptive Lagrangian sampling strategy has been deployed&lt;br&gt;in order to i) identify a fine scale structure of interest, ii) sample it at high spatial resolution the phytoplankton community, and&lt;br&gt;iii) follow the evolution of this structure and the related distribution of phytoplankton. The SPASSO software package uses&lt;br&gt;satellite altimetry, SST and surface Chl a concentration data to generate and provide near-real time daily maps of the dynamical&lt;br&gt;and biogeochemical structures present in the area. The sampling strategy was defined in order to cross a frontal zone separating&lt;br&gt;different types of water. Multidisciplinary in situ sensors (hull-mounted ADCP, a Seasoar towed fish and an automated flow&lt;br&gt;cytometer installed on the seawater supply of the Thermosalinograph) were used to sample at high spatial resolution physical&lt;br&gt;and biological variables. A particular attention was put in adapting the temporal sampling in different water masses to the&lt;br&gt;biological time scales in order to reconstruct the phytoplankton diurnal cycle.&lt;/p&gt;&lt;p&gt;&amp;#160;&amp;#160;&amp;#160; Such a strategy was successful in sampling two different water masses separated by a narrow front and characterized by&lt;br&gt;different aboundances of several phytoplankton species and functional groups. Consequently, our results highlight the role of&lt;br&gt;the front on the physical and biological coupling confirming previous modelling and remote-sensing studies.&lt;/p&gt;&lt;p&gt;&amp;#160;&amp;#160;&amp;#160; The new generation of altimetric satellite, SWOT, will provide a 2D sea surface height at an unprecedented resolution and&lt;br&gt;it will be a unique opportunity to better observe fine scale structures in the global ocean. Our methodology paves the way to&lt;br&gt;future in situ experiments that are planned in 2022 during the SWOT fast-sampling phase, few months after its launch.&lt;/p&gt;
