As sea level rose, the incised channels could include fluvial deposits, followed by estuarine and coastal deposits, and then finally marine sediments at the top. Profile extending east from Santa Cruz canyon showing characteristic paleoshoreline morphology with gently dipping abrasion platform that increases in slope moving landward. The location of change in slope is interpreted as the paleoshoreline.

1. Introduction

The upper transparent unit is interpreted as Holocene marine sediment. More chaotic sediment near the canyon edge could reflect a different depositional environment, such as an estuary. Several subbottom profiles revealed morphology associated with paleoshorelines. As in subaerial marine terraces, the transgressive surface was imaged and interpreted, identifying gently dipping abrasion platforms and more steeply dipping paleo-seacliffs.

Intersections of these surfaces are believed to represent paleoshorelines, formed during times of lower sea level.

In total, seven paleoshorelines were mapped around the NCI platform. Using a local sea level curve Clark et al. Many of the mapped paleoshorelines are buried beneath Holocene sediments and are not observed in modern seafloor bathymetry. Therefore, while useful over larger regions, models of paleoshorelines that use modern bathymetry may miss preserved paleoshoreline features and misinterpret the distance of modern shorelines and subaerial Paleocoastal sites from ancient shorelines Laws et al. However, the burial of submerged paleoshoreline features by Holocene sediments may also mean that archaeological resources are preserved in these locations.

1. Introduction

Several paleochannel features were also identified in subbottom profiling data within the Santa Cruz Channel. These paleochannels appear as irregular, chaotic, erosive surfaces below the transgressive surface that have a U- or V-shaped morphology Figure 6A. The features are filled with sediments that have a different character than the surrounding geology. One such feature was observed in the center of the Santa Cruz Channel, immediately northwest of the head of the submarine canyon.

The feature appears as a wide paleovalley with several smaller, V-shaped paleochannels within the valley Figure 6A. The channels and valley are covered by Holocene sediment of variable thickness. At the banks of the V-shaped channels, several subbottom profiles imaged high-amplitude dark anomalies that represent material different from the surrounding sediments. The channel margin location and acoustic character of the anomalies are similar to subbottom profiles from other areas e.

Around the world, submerged maritime landscapes represent one of the last frontiers for archaeologists working in island and coastal settings.

In the search for submerged terrestrial sites on the continental shelves of the Americas and around the globe, archaeologists, marine geologists, and other scientists must develop methods for effectively and efficiently narrowing search targets. The distribution of terrestrial archaeological sites along adjacent shorelines and other landforms, along with the careful mapping of paleoecological and paleoenvironmental resources that may have attracted human settlement, can be an effective first step e.

For late Pleistocene sites, the challenges grow with greater water depths and distances from shore. Offshore sonar mapping can target paleoshorelines and paleolandforms that may have been suitable for human habitation on the continental shelf that are within depths that can be sampled and ground-truthed. Sea floor coring can reach even relatively deep waters, although the sample size of such excavations is very limited. The next step in our research is the analysis of numerous sediment cores that targeted offshore paleochannels, high-amplitude reflectors, and possible paleosols identified in sonar imaging.

The results will help refine GIS modeling efforts and build best-practices in the search for early maritime peoples along the New World Pacific Coast and in similar regions around the globe. M15AC and our home institutions. TB conventionalized and drafted the manuscript.
