Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
Matlab code is included for detecting and tracking acoustic scattering layers from processed Echoview data. Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these...

Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these often dynamic, spatially complex features, so it is difficult to consistently and efficiently describe and...

Publication examines the wide variety of insect pests, diseases and environmental conditions that can affect Sitka Spruce along the coastline of Oregon.
Shore pine is a subspecies of lodgepole pine that inhabits the coastal strip in Oregon. Insect pests, diseases, and nonbiological (abiotic) factors may have an impact on growth, visual appearance, and productivity of trees. In this publication, we review the general nature of shore pine in Oregon and the common...
