    2025 | NOAA technical memorandum NOS NGS ; 99 | pdf
    Einstein’s theory of general relativity indicates that when any clock is operated at a location “higher” than another (“up” is measured away from the mass that generates the local gravity field) it will be observed to run faster. That is, it will appear to “tick” at a higher frequency to those observers “below.” In our everyday experience, this eff ...

    Harmful algal blooms (HABs) occur when algae or cyanobacteria produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. HABs can have adverse effects on human, animal, and ecosystem health, and cause significant economic impacts to coastal communities. Ranging from single-celled microalgae to large seaweeds, algae are ...

    2025 | Marine Mammal Science, 2025; 0:e70006 | PDF
    Tamanend's bottlenose dolphins (Tursiops erebennus) face population and environmental stressors that influence the age and length at sexual maturity (ASM and LSM, respectively) and calving interval, which are life history traits used to assess population status and health. We provide initial estimates of the ASM, LSM, and calving interval, as well ...
  • Calculating 3D rugosity maps for complex habitat scans
    Calculating 3D rugosity maps for complex habitat scans
    Beregovyi, Kindrat ;
    Dijkstra, Jennifer A.
    2025 | Front. Mar. Sci. 12:1449332 | PDF
    Advances in 3D scanning and reconstruction techniques, such as structure-from-motion, have resulted in an abundance of increasingly-detailed 3D habitat models. However, many existing methods for calculating structural complexity of these models use 2.5D techniques that fail to capture the details of truly 3D models with overlapping features. This p ...

    2025 | Journal of Climate, 38(6), 1477-1503 | PDF
    The need for skillful seasonal prediction of coastal sea level anomalies (SLAs) has become increasingly evident as climate change has increased coastal flooding risks. Here, we evaluate nine current forecast systems by calculating deterministic and probabilistic skill from their retrospective forecasts (“hindcasts”) over 1995–2015, for lead times u ...
