In Deeper Currents, Donald C. Jackson guides us on a journey into the cathedrals of wild and lonely places, those sacred spaces where hunters and fishers connect with the rhythms of the earth and the spirit that resonates within us. Jackson explores hunting and fishing as frameworks—sacraments—for discovering, engaging, and finding meaning. He invites readers to consider connections with wilder realms of being. Hunting squirrels on an autumn morning, probing the woods, rifle in hand, Jackson reveals an attention to nature too often neglected. Following a bird dog into the damp and mysterious places where woodcock settle on their southbound migrations; chasing hounds on the trail of raccoons on a frosty winter night; stalking deer in a quiet corner of a small farm; fishing for carp in a creek, bass and bluegill in ponds, catfish in a murky river, and reef fish in the Gulf, Jackson reminds that we are stewards of not only resources but also a past that defines us as hunters and fishers. We must pass this legacy along to the generations that follow. In Deeper Currents, tractors and old barns find a place in the reader's heart. Boats and canoes navigate realms of danger and dreams. Jackson shares outdoor pilgrimages with good friends in cabins, tents, camps, and old trailers tucked beyond the reach of a rushing world. He rejoices in the whisper of stiff wings as ducks come to decoys, the call of geese and cranes over tidal flats, the hush before a storm, the muffled snap of a twig at twilight, a drop of dew falling on the surface of a pond, and the clicking of caribou hooves on an Alaskan gravel bar. Jackson finds these natural moments fill us with energy. They remind us that we are taking part in a sacred heritage and that creation is unfolding all around us.

Ocean currents were measured in the central northeast Pacific, from 30 degrees N to 40 degrees N and 140 degrees W to 150 degrees W, with nine arrays of moored current meters during autumn 1973. Current meter records at depths from 700 m to 5420 m were analyzed to determine the characteristics of intermediate and deep currents within the central northeast Pacific. The currents in this region have very low speeds which generally decrease with increasing depth. Contributions to the time-dependent currents are primarily from oscillatory motions at the local inertial frequencies and the semidiurnal tidal frequency. Spectral analysis indicates that tidal frequency motion is essentially due to baroclinic internal tides and not barotropic surface tides.

Data assimilation is considered a key component of numerical ocean model development and new data acquisition strategies. The basic concept of data assimilation is to combine real observations via estimation theory with dynamic models. Related methodologies exist in meteorology, geophysics and engineering. Of growing importance in physical oceanography, data assimilation can also be exploited in biological and chemical oceanography. Such techniques are now recognized as essential to understand the role of the ocean in a global change perspective. The book focuses on data processing algorithms for assimilation, current methods for the assimilation of biogeochemical data, strategy of model development, and the design of observational data for assimilation.
