A position and wave spectra dataset of Marginal Ice Zone dynamics collected around Svalbard in 2022 and 2023.

Sea ice is a key element of the global Earth system, with a major impact on global climate and regional weather. Unfortunately, accurate sea ice modeling is challenging due to the diversity and complexity of underlying physics happening there, and a relative lack of ground truth observations. This is especially true for the Marginal Ice Zone (MIZ), which is the area where sea ice is affected by incoming ocean waves.

Fingerprints of El Niño Southern Oscillation on global and regional oceanic chlorophyll-a timeseries (1997-2022).

With the advancement of present-day ocean color satellites, the spatiotemporal variations of oceanic Chlorophyll-a (Chl-a) concentration, a proxy for phytoplankton population, can be monitored at regional and global scales. Estimating long-term changes in Chl-a concentration, however, is mainly constrained by the limited availability of ocean color data and the significant influence of climate oscillations like the El Niño Southern Oscillation (ENSO). In this study, we investigate the influence of ENSO on regional and global Chl-a timeseries using two ocean color datasets spanning from September 1997 to December 2022.

A dataset of direct observations of sea ice drift and waves in ice.

Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena and mechanisms that govern sea ice growth, drift, and breakup. To this end, we have gathered a dataset of in-situ observations of sea ice drift and waves in ice.

Feedback and Analysis System to Improve Partial Weight Bearing and Bone Healing Following Fractures and Osteotomies of the Lower Limb: Technical Note.

PURPOSE OF THE STUDY After the surgical treatment of injuries of the lower extremities or osteotomies, patients are frequently asked to partially load the affected leg during the first weeks of rehabilitation. The patient's compliance to the prescribed weight bearing limit and their ability to regain a physiological gait as soon as possible are necessary for a fast rehabilitation without complications. MATERIAL AND METHODS/RESULTS To support patients during this important phase of recovery, we developed a feedback and analysis system that is able to provide feedback concerning loading and roll over behavior to the patient.
