Impacts of Hypoxia on Zooplankton Spatial Distributions in the Northern Gulf of Mexico (Page 1)

Impacts of Hypoxia on Zooplankton Spatial Distributions in the Northern Gulf of Mexico

Roman MR, Pierson JJ, Kimmel DG, Boicourt WC, and Zhang X ·
2012

The northern Gulf of Mexico (NGOMEX) was surveyed to examine the broad-scale spatial patterns and inter-relationships between hypoxia (< 2 mg L-1 dissolved oxygen) and zooplankton biovolume. We used an undulating towed body equipped with sensors for conductivity, temperature, depth, oxygen, fluorescence, and an optical plankton counter to sample water column structure, oxygen, and zooplankton at high spatial resolution (1 m-vertical; 0.25-1 km-horizontal).

Spatial distribution of agricultural residue from rice for potential biofuel production in China

Elmore AJ, Shi X, Gorence NJ, Li X, Jin H, Wang F, and Zhang X ·
2008

In China, agricultural residues (particularly from rice) are widely used for energy and other applications, albeit on a localized scale and often at poor rates of efficiency. if some portion of this biomass were to be reallocated and transported to central biomass energy facilities, an initial component of the design process would be to gain an understanding of the spatial distribution of biomass production.

Investigating menhaden recruitment variability: Modeling the relationship between striped bass recovery and menhaden recruitment (Page 1)

Investigating menhaden recruitment variability: Modeling the relationship between striped bass recovery and menhaden recruitment

18 October 2006

This newsletter summarizes ongoing development of a model that describes fluctuations in the number of young menhaden within Chesapeake Bay. Using both menhaden spawning stock and striped bass predation potential, the model successfully accounts for most of the variability (~70%) seen in Chesapeake Bay menhaden recruitment.

Seasonal and annual variability in the spatial patterns of plankton biomass in Chesapeake Bay

Roman M, Zhang X, McGilliard C, and Boicourt W ·
2005

We conducted high-resolution, underway sampling in April, July, and October for 6 yr (1995-2000) in the large estuary, Chesapeake Bay. This period included climatological extremes in freshwater inputs that strongly influenced both the overall stocks and spatial distribution of phytoplankton and zooplankton. Higher biomass of both phytoplankton and zooplankton occurred in springs, when freshwater input into Chesapeake Bay was above the average discharge.

Latitudinal comparisons of equatorial Pacific zooplankton

Roman MR, Dam HG, Le Borgne R, and Zhang X ·
2002

Zooplankton biomass and rates of ingestion, egestion and production in the equatorial Pacific Ocean along 140degreesW and 180degrees exhibit maximum values in the High-Nutrient Low-Chlorophyll (HNLC) zone associated with equatorial upwelling (5degreesS-5degreesN) as compared to the more oligotrophic regions to the north and south.

Latitudinal Variations in Mesozooplankton Grazing and Metabolism in the Central Tropical Pacific During the Us Jgofs Eqpac Study

Zhang X, Dam HG, White JR, and Roman MR ·
1995

Pigment ingestion rates by three size classes of mesozooplankton (200-500 mu m, 500-1000 mu m and 1000-2000 mu m) within the euphotic zone were measured during the Survey 1 (February/March) and Survey 2 (August/September) cruises of the 1992 United States Joint Global Ocean Flux Study (U.S. JGOFS) in the central equatorial Pacific (EqPac).
