What are the differences between available and accessible data? #lovedata26 #accessibility
Access and Data: What are the differences between available and accessible data? Available; user benefits: locate and retrieve data. Guiding principles: findable, accessible, interoperable, and reusable (FAIR). Limitations: data sharing restrictions, user permissions, and paywalls. Accessible; user benefits: use, navigate, and understand data. Guiding principles: perceivable, operable, understandable, and robust. Limitations: user interfaces, software incompatibility, and formatting.

💧Did you know that the single-year severe drought of 2002 was not unprecedented in comparison with multi-year persistent droughts?🌳Learn more from David Meko & Katherine Hirschboeck's tree-ring study at doi.org/10.25422/azu....

Verde River Basin Comparison of Observed, Reconstructed, & Instantaneous Peak Flows. Plotted for each year are the observed mean annual flow (dark blue line) and the tree-ring reconstructed mean annual flow (magenta line) in cubic meters per second (cms) for the Verde River7 (scaled on the right axis). Also plotted is the instantaneous annual peak flow (vertical bars) in cms, (scaled on the left axis). The instantaneous peaks are classified and color coded to show the hydroclimatic cause of each event. The tree-ring core inset depicts a wide ring occurring within an otherwise narrow-ring sequence during the 1950s drought.

🌱💨Did you know taking soil samples can disturb the #soil and skew the results? Gil-Loaiza et al. developed a solution to this. Learn more from their dataset & article at doi.org/10.25422/azu... & doi.org/10.5194/bg-1.... Image: Gil-Loaiza et al. (2022) #OpenData #OpenScience #SoilHealth #SoilGases
Detailed schematic of sampling System 1 (UA) and System 2 (ARI). Column matrix gas concentrations were controlled by mixing cylinder gas with UZA using MFCs and delivering the custom gas mixture through the columns from bottom to top (dotted orange line). Probe sampling flow rates were controlled precisely using three MFCs to ensure that flow in and out of the probe was balanced (probe flow (blue lines) + dilution flow (red lines) is equal to total flow to analyzer (black lines)). Column headspace (atmospheric pressure) and control gas bypass (positive pressure) were controlled by MFCs at two points (dilution, total flow to analyzer), forcing the probe flow as a makeup flow (probe flow is equal to total flow minus dilution flow).

🌍 Did you know Earth’s surface still moves today because of ancient shifts in Earth’s inner structures? Calvelage et al. show more. See their dataset & article at doi.org/10.25422/azu... & doi.org/10.1098/rspa.... Image: Calvelage et al. (2024). CC BY 4.0. #OpenData #OpenScience #Tectonics
A graphic representation showing dynamic uplift and dynamic subsidence within an oceanic region from viscous stresses due to mantle upwelling and downwelling, known as dynamic topography (modified from [3]; K Czarnota 2022, personal communication). The seafloor deepens at a known rate as the ocean lithosphere cools and becomes older, shown here by its relative distance from the mid-ocean ridge. Dynamic topography is inferred in regions where the seafloor is anomalously shallower or deeper relative to the expected seafloor depth.

🔭🪞 Did you know tiny flaws in #telescope mirrors’ shape can cause telescopes to produce blurry images? Chalifoux et al. developed an innovative solution to this.

Fig. 1. a) Ultrafast laser stress figuring (ULSF) entails focusing an ultrafast laser at multiple depths in a mirror substrate, with coating on top (shown here) or bottom, depending on the coating. The stress induced by the laser spots bends the substrate to match the target shape. b) Process flow for applying ULSF to achieve a desired deformation of an optical surface. The stress calculator, recipe calculator, calibration procedure, and laser processing system are each described in the text.

Dorymyrmex bicolor engage in more social interactions than D. insanus. (A) Schematic of behavior method with pairs of ants filmed in a glass petri dish for 3 min and interactions coded in BORIS (Friard and Gamba, 2016). (B) Stills from recordings showing D. bicolor engaging in biting (left) and grooming (right) behaviors. In comparisons of nestmate interactions or non-nestmate interactions between species, D. bicolor interact more often than D. insanus (C). In comparisons of nestmate and non-nestmate behavior within species, D. bicolor non-nestmates display significantly more aggressive interactions (D) and significantly fewer affiliative interactions (E) than nestmates, an effect not detected in D. insanus. D. bicolor nestmates participate in antennation for longer duration bouts (F) and a greater amount of total time than non-nestmates (G); D. insanus nestmates and non-nestmates show comparable antennation bout duration and total time. (H) Dorymyrmex insanus display few trophallaxis events with no differences among nestmate or non-nestmate pairs, whereas D. bicolor nestmates engage in trophallaxis more frequently than non-nestmates. Statistical comparisons in (A–E,H) were made using a generalized linear model with a Poisson distribution followed by ANOVA and post hoc comparisons using Tukey’s Honestly Significant Difference. Statistical comparisons in F and G were made using pairwise Mann-Whitney U-test between non-nestmate and nestmate pairs of a species. *p < 0.05; ***p < 0.001; Color code for data point in (C–H): D. insanus cyan; D. bicolor blue.
